## Course Description

This course is mainly considered as an introductory course in the field of Gas Dynamics or Compressible Fluid Flow. In general, you will be exposed to various important aspects of compressible fluid flow, for e.g., when do one assume the fluid flow to be compressible, regimes of compressible fluid flow, mathematical formulation and analysis of isentropic flow and non-isentropic flows, etc.
