1993 Catalog Data: 14-650-432: Mechanical Engineering Laboratory
II (1)
Prerequisite: 14-650-282; 312; 350
Comprehensive experiments in fluid dynamics, heat transfer, acoustics
power system, and dynamic mechanical systems. Preparation of test procedure,
data analysis and presentation of reports and conclusion.
Textbook: None
Coordinator: K.T., Rhee, Associate Professor of MAE
Goals:
The objectives of this course are twofold: to give the students the
opportunity to test the theoretical knowledge on thermodynamics, heat transfer
and and vibration with experiments, and to permit the student to deliver
a technical presentation on laboratory results to their classmates in a
formal manner.
Prerequisites by Topic:
- Thermodynamics and heat transfer
- Mechanical measurements
- Fluid mechanics
Laboratory Projects:
- Report required for each experiment by every individual.
- Measurement of the NTU. Use a counter-flow heat exchanger and compare
with its theoretical value. Explain any discrepancy (three weeks).
- Forced convection. Measure Stanton and Nusselt numbers. Measure friction
factor. Use standard equations to compute those values. Compare results
and discuss discrepancies. Compare Sider-Tate and Colburn relations (three
weeks).
- Single degree of freedom vibration. Measure the natural frequency of
a one degree of freedom mass-spring system to compare with the calculated
value. Use a fast data acquisition system and learn to transfer the data
to a computer for subsequent analysis (three weeks).
- Pneumatic control experiment. Learn the response characteristics and
feedback loop concept of dynamic system using a simplified apparatus that
can be configured to produce first through fourth-order system (three weeks).
- Oral presentation of Laboratory results. Learn and practice the formal
technical presentation by following major steps of preparation, including
making visual aids and graphic materials for effective delivery of a talk.
