Two-Dimensional Irrotational Transonic Flows of a Compressible Fluid

Two-Dimensional Irrotational Transonic Flows of a Compressible Fluid

Date: June 1948
Creator: Kuo, Yung-Huai
Description: The methods of NACA TN No. 995 have been slightly modified and extended in include flows with circulation by considering the alteration of the singularities of the incompressible solution due to the presence of the hypergeometric functions in the analytic continuation of the solution. It was found that for finite Mach numbers the only case in which the nature of the singularity can remain unchanged is for a ratio of specific heats equal to -1. From a study of two particular flows it seems that the effect of geometry cannot be neglected, and the conventional "pressure-correction" formulas are not valid, even in the subsonic region if the body is thick, especially if there is a supersonic region in the flow.

Two-Dimensional Subsonic Compressible Flows Past Arbitrary Bodies by the Variational Method

Two-Dimensional Subsonic Compressible Flows Past Arbitrary Bodies by the Variational Method

Date: March 1951
Creator: Wang, Chi-Teh
Description: Instead of solving the nonlinear differential equation which governs the compressible flow, an approximate method of solution by means of the variational method is used. The general problem of steady irrotational flow past an arbitrary body is formulated. Two examples were carried out, namely, the flow past a circular cylinder and the flow past a thin curved surface. The variational method yields results of velocity and pressure distributions which compare excellently with those found by existing methods. These results indicate that the variational method will yield good approximate solution for flow past both thick and thin bodies at both high and low Mach numbers.
