DISCONTINUOUS PLOWS AND FREE STREAMLINE SOLUTIONS FOR AXISYMMETRIC BODIES AT ZERO AND SMALL ANGLES OF ATTACK

摘要

Except for a few numerical results, nothing has been published, comparable in magnitude to the two-dimensional case, concerning free streamline solutions of the axisymmetric problem. Since the method of using conformal transformations is not available in axisymmetric and three-dimensional flows, it is necessary to adopt approximate methods for the free streamline analysis.nIn this study an integral equation procedure has been applied to calculate the free streamline flow behind axisymmetric bodies at zero and small angles of attack. The method uses a modified condition for irrotational flow and iterates until the proper streamline location is found. Some of the results obtained by this procedure will be discussed in this report.
