Course Objectives

Sound understanding of fundamentals of compressible fluid flow. Calculate thermodynamic and aerodynamic properties across normal and oblique shock waves and expansion fans. One-dimensional analysis of compressible flow in nozzles and diffusers. 1-D flow with heat addition (Rayleigh flow) and friction (Fanno flow). Solving linearized subsonic and supersonic compressible flow equations.
