A CFD code for simulation of 3D inviscid throughflow in turbine stages will be presented in this paper. The discretization is realized by a finite difference method applying a transformation procedure. The time dependent Enter equations are solved by the explicit time marching method of Lax, Wendroff and Richtmyer. The coupling between stator and rotor flow is achieved by circumferentially averaged flow data, enabling the simulation of low frequency flow fluctuations. The flow through a gas turbine stator is simulated by the code. In this case secondary flow phenomena caused by a nonuniform inlet flow are of special interest. A throughflow calculation of the last stage of a LP steam turbine shows that the program is able to manage 3D complex transonic flows as well. The CFD results are compared in both cases with experimental data. |
