On the Characterization of Fields of Diabatic Flow. Part I. General Theory of Steady Diabatic Flow

摘要

The vector representations of fields of steady, rotational, diabatic compressible flow are first studied in order to find that representation which is most efficient. Diabatic flows are then introduced which are irrotational in the sense that the velocity is a compound lamellar vector. These flows are characterized in terms of their character and form, specified respectively by the function g(N) and the form function F(phi sub N) which occurs in the partial differential equation for the potential function phi sub N. The type of the differential equation for phi sub N is found to depend only upon the flow character which in addition fixes the relationship between the heat addition function q sub N, the geometry of the stream tubes and the form function.
