Description
Compressible flow: concept of waves in fluid, mach waves, compression waves, expansion waves. Basic flow features: isentropic flow, shock waves, stationary and moving shocks, oblique shocks, bow shocks, expansion fans. Example flows: flow around bodies, shock expansion method for flow over airfoils. Flow through a nozzle: convergent nozzles, CD nozzles, exit pressure variation vs stagnation pressure variation. Oblique shock wave reflections, Jet flows Under- and over-expanded flows shear layers. Flow with friction, friction choking. Flow with heat addition, thermal choking. Supersonic combustion. Shock tube, supersonic wind tunnel, flow visualization, supersonic probes. Design of nozzles, external flow around bodies. Experimental characteristics of airfoils in compressible flow. Unsteady flows. (from nptel.ac.in)
