A METHOD FOR THE CALCULATION OF THE LAMINAR AND TURBULENT BOUNDARY LAYER AROUND TWO-DIMENSIONAL AND AXISYMMETRIC BODIES WITH SUCTION OR BLOWING.

Abstract

Imcompressible fluid of steady flow around twodimensional and axisymmetric bodies is assumed. Method of calculation for the laminar and turbulent boundary layer momentum thickness with arbitrarily distributed suction or blowing is developed, starting from the energy theorem instead of the momentum theorem. By giving proper form for the suction or blowing velocity distribution, momentum thickness is expressed by the summation of two terms, one given for the impervious case and the other produced by the existence of suction or blowing velocity distribution on the surface of the body. For the evaluation of the impervious term, Truckenbrodt's method is used. As examples of the application of the method, an elliptic cylinder for a two-dimensional case and a spheroid for an axisymmetric case of fineness ratio 0.3 are used for both laminar and turbulent cases.
