Heat Delivery in a Compressible Flow and Applications to Hot-Wire Anemometry.

摘要

In a two-dimensional field a generalized potential theory applicable to nonadiabatic and rotational flow is developed. Three partial differential equations are first obtained determining the three variables which are: Distribution of additional temperature, velocity perturbation, and an auxiliary function, characterizing the rotationality of the flow. With the use of this theory the action of heat sources on the flow is studied, and the heat delivery in a compressible flow at subsonic and supersonic speeds is calculated. The results show the effect of compressibility and the nonlinear cooling. Applications of the results to hot-wire anemometry are discussed.
