Fundamentals of Gas Dynamics

Fundamentals of Gas Dynamics. Instructor: Dr. A. Sameen, Department of Aerospace Engineering, IIT Madras. The course introduces compressible flow and its constitutive equations. The physical concepts behind isentropic flows, area-Mach number relation etc will be discussed with practical problems in mind. Properties of shocks and expansions are important parts of this course. All the numerical examples will be in SI units. (from nptel.ac.in)
