ME 882 - Compressible Flow

3 lecture hours 0 lab hours 3 credits
Course Description
This course covers one-dimensional gas dynamics; shocks and waves, two-dimensional flows, perturbation theory; similarity rules, effects of viscosity and conductivity. The course culminates in a computer project in which a supersonic nozzle will be designed using the method of characteristics. (prereq: graduate standing and ME-317 or equivalent)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• Apply engineering principles and analyze problems dealing with compressible flow and gas dynamics
• Compare shock expansion with linearized theory for subsonic and supersonic flow over airfoils
• Design a supersonic nozzle using the method of characteristics
