THE INFLUENCE OF OUTLET SYSTEM GEOMETRY ON TESLA TURBINE WORKING PARAMETERS
Author / authors
The paper presents an analysis of the influence of Tesla turbine outlet system geometry on parameter distribution and power. Simulations were carried out with the aid of Ansys products: DesignModeler, Meshing and CFX 17.0. The model geometry was based on the dimensions of existing turbine. Three different types of outlet system were investigated. A mesh independence study was carried out in order to obtain results which were unaffected by discretization method. Computations were performed using experimental data. The flow phenomena occurring inside the turbine are described in addition to the differences caused by outlet system geometry. Numerical results were confronted with experimental analysis.
