SG3113 Compressible Aerodynamics 9.0 credits
Kompressibel strömningsmekanik
The course will primarily be based on selected parts of the book by John D. Andersson, Modern Compressible Flow, Mc Graw Hill , 1990, from which may be cited:
"This book deals exclusively with that "marked departure", i.e., it deals with compressible flows, in which the density is not constant. In modern engineering applications, such flows are the rule rather than the exception. A few important examples are the internal flows through rocket and gas turbine engines, highspeed subsonic, transonic, supersonic, and hypersonic wind tunnels, the external flow over modern airplanes designed to cruise faster than 0.3 of the speed of sound, and the flow inside the common internal combustion reciprocating engine. The purpose of this book is to develop the fundamental concepts of compressible flow, and to illustrate their use."

Intended learning outcomes
Finishing this course the student should know how to:
 derive the conservation laws of mass, momentum and energy of inviscid, compressible flow and apply them to various fluid dynamical problems to e.g.
 analyse the interaction of forces between solid boundaries and flowing gases from the basic principles of compressible flow
 analyse the energy conversion process in a flowing gas from the thermodynamic principles of isentropic and irreversible flow respectively
 interpret results from performed experiments  demonstrate a physical understanding of the mathematical formulas derived
 give a physical description of the special effects appearing in hypersonic flows.
 explain the consequences of the effects of compressibility on the flow in a viscous boundary layer
Course main content
For an inviscid, compressible gas the students should be able to
 calculate pressure, velocity and temperature for quasi onedimensional, stationary, isentropic flow
 calculate changes of pressure, velocity and temperature over normal and oblique shock waves
 calculate changes of pressure, velocity and temperature in simple expansion waves
 calculate pressure, velocity and temperature for unsteady, onedimensional, nonlinear waves
 calculate the flow field in linear theory for subsonic and supersonic flow around bodies
 understand how pressure and drag on a body changes in transsonic flow
 derive the conservation equations governing the flow of compressible fluids in boundary layers
 derive solutions to the boundary layer equations for some cases demonstrating the main features of compressible flow in a boundary layer
