The Department of Mechanical and Aerospace Engineering of the Case School of Engineering offers programs leading to bachelor's, master's, and doctoral degrees. It administers the programs leading to the degrees Bachelor of Science in Engineering with a major in mechanical engineering, Bachelor of Science in Engineering with a major in fluid and thermal engineering sciences and Bachelor of Science in Engineering with a major in aerospace engineering. All three curricula are based on four-year programs of preparation for a productive engineering career or further academic training. The mechanical, and fluid and thermal majors are accredited by the Engineering Accreditation Commission of the Accreditation Board for Engineering and Technology (ABET), and the aerospace major is awaiting review for accreditation during the next regular visit by ABET.
The academic and research activities of the department center on the roles of mechanics, thermodynamics, heat transfer, and engineering design in a wide variety of applications such as aeronautics, astronautics, energy, environment, materials and stresses, biological systems, machinery dynamics, and tribology. Particularly important is the joint activity with the Departments of Biomedical Engineering and Orthopaedics of the School of Medicine in orthopaedic engineering and the Departments of Civil Engineering and Systems Engineering.

Civilization, as we know it today, depends on the intelligent and humane use of our energy resources and machines. The mechanical engineer's function is to apply science and technology to the design, analysis, development, manufacture, and use of machines that convert and transmit energy, and to apply energy to the completion of useful operations.
To prepare mechanical engineers for these tasks, The Case School of Engineering curriculum builds a four-year program with emphasis on applied mechanics, fluid and thermal engineering, and mechanical design, with diversification in other areas pertinent to the students' interests.
The fluid and thermal engineering sciences are significant not only for modern technology but also for many phenomena related to the association of man with his environment. The importance of this field to aeronautics and astronautics is readily apparent, but it is also important to many other areas of technology such as power generation and lubrication.
Physicochemical transport phenomena is a subject that has developed at the interface between physics and chemistry. It is concerned with problems raised by the effects of fluid motions on chemical and physicochemical transformations and by the effect of physicochemical factors on the motion of fluids. As such this subject has considerable significance to many important problems of current interest such as materials processing; electrochemical processes; energy storage; pollution; oil recovery; and biological, physiological, and geological phenomena.
The educational program in fluid and thermal engineering sciences takes cognizance of a broad scope of applications and is fundamental and comprehensive. The interdisciplinary nature of the field is continually stressed, and the subject matter is made relevant to various areas of importance.
Aerospace engineering has grown dramatically during the past decade with the introduction of the computer as a fundamental tool for data collection and control. The wealth of scientific information developed as a result of aerospace activities forms the foundation for the Aerospace Engineering major. Scientific knowledge is being developed each day from the Shuttle, Space Station Freedom, and the National Aerospace Plane Programs. New methods of analysis and design for structural, fluid, and thermodynamic applications are required to meet these challenges.
The Aerospace Engineering major has been developed to address the needs of those students seeking career opportunities in this highly specialized and advancing field. While this program is not recommended for everyone, it is a challenging program for those who know they want to enter the aerospace industries.

The education and research philosophy of the Department of Mechanical and Aerospace Engineering for both the undergraduate and graduate programs is based on a balanced operation of analytical, experimental, and computational activities. All three of these tools are used in a fundamental approach to the professional activities of research, development, and design. Among the major assets of the department are the experimental facilities maintained and available for the faculty, students, and staff.
The introductory undergraduate courses are taught through the Robert M. Ward '41 Laboratory. This central facility is modular in concept and available to the student at regularly scheduled class periods to conduct a variety of prepared experimental assignments. The lab is equipped with a variety of instruments ranging from classic analog devices to modern digital computer devices for the collection of data and the control of processes. Advanced facilities are available for more specialized experimental tasks in the various laboratories dedicated to each specific discipline. Most of these laboratories also house the research activities of the department, so the students are exposed to the latest of technology in their prospective professional practice. Finally, every undergraduate and graduate degree program involves a requirement, i.e., Project, Thesis or Dissertation, in which the student will be exposed to a variety of facilities of the department.
The following is a listing of the major laboratory facilities used for the advanced courses and research of the department.
Among the major facilities in fluid and thermal engineering sciences are a low-turbulence sub-sonic wind tunnel, a low-turbulence water tunnel, an internal combustion engines laboratory, an acoustics facility, a material flammability testing facility, a refractive index matched multiphase flow test loop for solid-liquid slurry flows, a test facility to study particle laden jet-flow interactions, and a 50KW arc image furnace. The laboratories are well equipped with high precision flow and temperature measuring equipment such as hot-wire and hot-film anemometers, laser doppler velocimeters, laser vibrometers, and particle dynamics analyzer. Under a variety of special joint programs, many students perform their experiments in laboratories at the NASA Lewis Research Center.
A laser diagnostics laboratory is directed toward investigation of: complex flow and transport problems, flow induced vibrations, and statically and dynamically excited structural vibrations, with an emphasis on understanding the underlying phenomena. The research currently being conducted in this laboratory includes: the study of the mixing phenomena involved in the injection of a particle laden jet into cocurrent flows, spray characterization and droplet interactions, study of solid liquid dense slurries, techniques to discriminate particle size using laser velocimetry, investigation of oscillatory flows in stirling engine, (improvement of performance), development of new flow injectors for two phase flows, particle image velocimetry (PIV) for multiphase flows, and blade stress and vibration measurements. The laboratory has several laser velocimeters, including two two-component Argon ion based laser velocimeter systems, a Particle Dynamics Analyzer (Phase Doppler Interferometer/Doppler Velocimeter) to simultaneously measure particle velocity and size, a PIV system. Four laser vibrometer systems, acquired through a grant from the National Science Foundation, are the nucleus of the undergraduate vibrations laboratory. The computer facilities dedicated to the laboratory include many 486 system PCs for data acquisition and a Silicon Graphics 3020 IRIS workstation.
The Microgravity Laboratory is dedicated to research in fluid and mechanics and heat transfer in microgravity, such as that found on the Shuttle in flight. This activity is directed toward a fundamental understanding of thermocapillary flow, double-diffusive convection, and convection in float-zone crystal growth process. It is equipped with various temperature measurement instruments, a Schlieren System, a data acquisition system, a S-VHS video system with interchangeable lenses, and various photographic equipment for flow visualization studies.
The major facility for the experimental study of the solid mechanic behavior of statically and dynamically excited structural elements and mechanical devices is the new Daniel K. Wright, Jr., Laboratory for Experimental Mechanics. This facility evolved from the Experimental Stress Analysis Laboratory which included equipment for brittle lacquer, photoelastic, and strain gage studies. The lab was renovated and equipped using funds from the department's Connelly Educational Fund. The laboratory will house the new Schenck-Pegasus Digital Servo Controlled Hydraulic Testing System. This facility includes a 20 kip Universal Testing Frame with grips and instrumentation for testing under load, displacement, or strain control. A second testing unit of this facility is constructed around a seismically isolated 3' x 5' test bed with specialized fixtures for the static and dynamic testing of structural components and mechanical devices. The laboratory is also equipped with digital computers dedicated to the collection of data and the control of complex experiments.
The department facilities also include several specialized laboratories supported under grants from the General Motors Foundation. The G.M. Engines Laboratory is a modern facility for measuring the dynamic performance of internal combustion engines while monitoring the behavioral parameters such as temperatures, pressures, stresses, velocities, and displacements. The two test cells can be operated completely by remote control with all data collected by digital computer. The Dynamics and Controls Laboratories of the department was also provided by a grant from the General Motors Foundation and includes a Components Laboratory for characterizing mechanical, electrical, hydraulic, and pneumatic components. The Robotics and Controls Laboratory includes a Yasakawa 5-Axis Robot, a gift of the Nordson Corporation, several computer workstations, a tread-mill, and other facilities for the development of walking robots. Finally, the Rotor Dynamics Test Facility has equipment for measuring the vibration characteristics of seals and bearings and a high-speed (15000 RPM) flexible rotor test rig.
In Orthopaedic Engineering, the department has a Biomechanical Testing Laboratory with two Instron Mechanical Test machines, and several specialized test apparatus. There is also a soft tissue testing lab with several standard and special test machines, and an Instrumentation Laboratory devoted to the task of measuring these behavior parameters. A Biomechanical Computations and Design lab utilizing computer workstations has recently been added. In addition, it shares many research facilities with University Circle area hospitals.
Well-equipped, manned central shops and instrument rooms are available, as well as a controlled-environment room for experiments requiring extreme precision.
The Computer Aided Engineering Laboratory (CAEL) includes a Local Area Network (LAN) server available through 14 independent 486 IBM compatibles and 5 independent 386 IBM compatibles. Four of the 386 machines are mounted on mobile laboratory carts and equipped with data acquisition and control adapters, as well as sophisticated software for on-site data analysis. A final 386 machine is devoted to finite element analysis. The CAEL LAN runs a variety of software packages specifically geared towards the needs of the Mechanical and Aerospace students.
All of the laboratory's computers have Internet access through the campus network, allowing students to use various supercomputers as well as local, national, and international electronic mail. This network also makes several other campus wide LANs available, where students have immediate access to a large variety of software used across campus.
