Compressible Flow I
Pennsylvania State University-World Campus · UGRD · Fall 2026
Catalog description
This course is a technical elective. We cover several unique concepts and applications of compressible flow, including: speed of sound and Mach number, isentropic 1-D flow in variable area ducts, converging nozzles, choking, converging-diverging nozzles, moving shocks, blast waves, shock tubes, Rayleigh flow (duct flow with heat transfer), Fanno flow (duct flow with friction), normal and oblique shock waves, expansion fans, and other topics to be announced, time permitting. Course Objectives: Upon completion of this course, students should be able to: 1. Solve a range of compressible-flow problems often encountered in engineering practice, including adiabatic isentropic flow in ducts and normal and oblique shock wave analysis. 2. Apply physical thinking and problem-solving techniques to practical problems using fluid mechanics and thermodynamics. 3. Integrate previous course material in fluids and thermodynamics into the study of compressible flow. 4. Apply computer programs (Matlab, Excel, EES, Javascript calculators, etc.) to compressible-flow problems. 5. Identify and utilize the strong visual nature of flow patterns in engineering practice in the thermal sciences. 6. Demonstrate practical design skills such as design of supersonic nozzles and wind tunnels. 7. Demonstrate professionalism and respectful interaction with faculty and colleagues.
