Gas Dynamics

Instructor: Dr. T.M. Muruganandam, Department of Aerospace Engineering, IIT Madras.

This course discusses topics in gas dynamics. Review of fundamentals: concepts from fluid mechanics, basic thermodynamic relations. Compressible flow: the concept of waves in a 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 incompressible flow. Unsteady flows.
