A Study of Hybrid Computing Techniques for Transonic Flow Fields.
T. C. Adamson, Messiter Jr., A. F. · 1980
Two problems in which analytical solutions might be used to improve the accuracy of or reduce the computation time of numerical computations are considered. In the first, axisymmetric flow at large distances from a slender body is studied for supersonic and transonic speeds, and the length scales for which viscous effects become important are derived in terms of the slenderness parameter and the Reynolds number. An analytical solution is obtained for a case which appears most likely to be important at supersonic speeds. In the second, solutions are derived for transonic flow in a two-dimensional channel with a shock wave, at low Reynolds number. A relationship is derived from which the effects of Reynolds number on the position of the sonic line within the shock wave can be found. (Author)
