NUMERICAL INVESTIGATION OF THE SECONDARY FLOW DEVELOPMENT IN TURBINE CASCADE

Abstract

The results represent the first attempt of the numerical analysis of 3-D secondary flows formed in the linear turbine cascade wind tunnel. Numerical simulations were carried out by means of the SPRC code [1]. It was possible to make the calculations presented here thanks to the cluster of PC’s providing sufficient computational resources. In order to be able to verify the obtained results the case considered is the workshop test case [2]. It has been shown that the obtained results are in very good agreement with experiment. This gave confidence in the results and several important conclusions concerning the development of streamwise vortices could be made thanks to the work carried out.
