abstract

Time marching solutions of transonic flow are widely used for the analysis of turbomachinery cascades. Attempts to increase efficiency, accuracy and computational speed are, at present, the main goal of research in the field of two dimensional flow. The aim of the paper is the presentation of a new pseudo-time dependent method to try to achieve these goals. The method, basic idea and procedure used to develop the new formulation are described and discussed in brief. Some applications of the method to transonic turbine cascades are presented against experimental results. The accuracy and speed of the method is discussed and possibilities for further developments are shown.
