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 variable which are: Distribution of additional temperature Theta, velocity perturbation Pi, and an auxiliary function Kappa 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.
