Theory of Flows in Compressible Media with Heat Addition,
Abstract
A systematic survey is undertaken of the theory of the effect of a given heat addition on the flow of a compressible medium. Here steady flows, both one-dimensional and multi-dimensional, linear and nonlinear, are treated. Consideration is given to addition of mass and momentum to a streamtube as well as of energy. Interesting equivalences arise here. The heat can be distributed continuously in the flow field or added at fronts. For practical applications, the reduction of the drag of a body in flight by heat addition in the flow field is important. At extremely high velocities the problem arises of propulsion by external combustion. Here, the energy is to be transferred directly to the flowing medium, at the high velocity. For the evaluation of such an energy addition, reference is made to the propulsive efficiency, as well as the lift and drag of the body.
