Fundamentals of Gas Dynamics

Indian Institute of Technology Madras and NPTEL via Swayam

This course may be unavailable.


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.
INTENDED AUDIENCE : Undergraduate students of Mechanical and Aerospace EngineeringPRE-REQUISITES : Thermodynamics and fluid mechanics
