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, linearized velocity-potential equation. The course culminates in a computer project in which a supersonic nozzle will be designed using the method of characteristics. (prereq: 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
