Relaxation Solutions for Three-Dimensional Transonic Flow through a Compressor Blade Row, in the Nonlinear Small-Disturbance Approximation.
Abstract
A relaxation method for calculating the three-dimensional transonic flow through a compressor blade row is discribed. The flow is taken to be steady in blade-fixed coordinates, and is treated in the nonlinear small-disturbance approximation. Details of the finite-difference formulation and the solution procedure are given. The resulting computer code is capable of operating in either of two modes: in the first, the user specifies the complete blade shape and the operating conditions, and the program finds the complete flow field, including the loading distribution on the blades. In the second, the user specifies the loading distribution over the blade surface, and the thickness distribution of the blades. The program then finds the three-dimensional flow field, including the shape of the camber surface about which the prescribed thickness must be symmetrically distributed, in order to produce the prescribed loading. Results of demonstration calculations illustrating each of these modes are included. (Author)
