course Name : Compressible fluid flow
CATALOG DESCRIPTION:
Shock and expansion waves, quasi-one-dimensional flow, supersonic wind tunnel operation, linearized flow,
and compressibility effects on aerodynamics of airfoils and bodies.
COURSE OBJECTIVES:
1) Introduce the basic elements of compressible fluid flow, including one-dimensional and quasi-one-
dimensional theory, 1-D flow with friction and heat addition, shock and expansion waves, and
aerodynamics of slender bodies.
2) Develop a strong understanding of the physics underlying these topics.
3) Develop and apply mathematical tools necessary for solving compressible flow problems.
KNOWLEDGE, SKILLS, AND ABILITIES STUDENTS SHOULD HAVE BEFORE ENTERING
THIS COURSE:
Knowledge of thermodynamics, incompressible fluid mechanics, differential and integral calculus, ordinary
differential equations, and some knowledge of partial differential equations. The students should also have
experience with computer spread sheet and engineering graphics software.
KNOWLEDGE, SKILLS AND ABILITIES STUDENTS GAIN FROM THIS COURSE:
The students will gain knowledge of the basic elements of compressible fluid flow. Compressible flows are
high speed flows in which the fluid velocities are appreciable compared to the velocity of sound so that
variations in pressure, temperature and density are significant. Knowledge of compressible flow
fundamentals is essential for understanding high speed aircraft and missile aerodynamics, gas turbine
engines, rocket engines, re-entry vehicle design, supersonic wind tunnel design, aerodynamic heating and

drag, etc. In this course we will concentrate on inviscid flows - in practice there are many important flows in
which we are able to ignore viscosity with little loss of accuracy. Initially, we will derive the fundamental
equations governing compressible flow. We will then use these to examine a variety of fundamental and
physically important features of compressible flow including: a) one-dimensional and quasi one-dimensional
flows, with and without heat transfer and friction, b) flows through normal shock waves, oblique shock
waves and expansion waves, c) wave reflections and interactions, d) flows in nozzles, inlets and diffusers, e)
aerodynamics of slender bodies.
