Before choosing courseSG2215 Compressible Flow 7.5 creditsAdministrate About course

The course will 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, high-speed 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."

Content and learning outcomes

Course contents

For an inviscid, compressible gas the students should be able to

  • calculate pressure, velocity and temperature for quasi one-dimensional, 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, one-dimensional, non-linear 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

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.
