A COMPARISON OF METHODS FOR COMPUTING THE VELOCITY DISTRIBUTION AND THE BOUNDARY LAYER ON BODIES OF REVOLUTION

Abstract

This report represents an analytical and experimental study into the solution of flow around a body of revolution. The flow outside the boundary layer was assumed to be a perfect fluid and was explored by potential flow methods. The flow inside the boundary layer was explored by boundary layer methods admitting the predominance of viscosity. The potential flow methods include von Karman's method, used as a representative of the singularity distribution, and Kaplan's, which is regarded as being one of the more accurate methods. In connection with Kaplan's method, Young's method, which is a modification of Kaplan's method, is also discussed. In addition to these and for comparison, the two-dimensional case is also chosen. For ease of calculation, spheroids of various fineness ratios are used. Especial emphasis is put on the spheroid of fineness ratio 0.3 as the representative of the spheroid. A calculation method for both the laminar and turbulent flow, Truckenbrodt's method, is chosen as the representative method for calculation of the turbulent boundary layer. For comparison, other methods are given.
