Numerical tests of threedimensional flow in a transonic turbine
Abstract
A computation scheme for plane cascades and cascades of the general surface of revolution is generalized to three dimensional flow, starting from the integral form of the basic equations. A computer program was developed and the preliminary results of numerical tests are presented. Comparison between the numerical solutions of quasithree dimensional and fully three dimensional flows indicates that the quasithree dimensional assumptions may lead to significant errors. This confirms the necessity of fully three dimensional calculation. If about 2000 grid points are assigned, 100 minutes is required to calculate one case on the 013 computer. From the application point of view, this is not considered to be excessive run time.
