Threedimensional inviscid turbomachinery flow simulations obtained by solving the Euler equations on an OH type grid
Abstract
A computer code for calculating the steady inviscid flow in a rotating system (turbomachinery) by solving the 3dimensional Euler equations on an OH type grid is developed. The numerical method is an explicit, centered finitevolume scheme. The method includes an artificial viscosity model and a local time step technique. The explicit time integration scheme is a onestep, threestage RungeKutta method. The generation of the grid is done by transfinite interpolation. The grid used has an OH type structure which gives good resolution at the leading and trailing edges. Different geometries were used under different flow conditions. Results for three different turbine blades are presented. Comparisons between experimental data and other Euler solvers show the accuracy of the code.
