Mastering the calculation methods of flow prediction in complex geometries of turbomachinery.

Mastering the calculation methods of flow prediction in complex geometries of turbomachinery.

Three-dimensional non-viscous flow in blade cascades - methods in meridian section, methods of solving from blade to blade, combined solution, numerical solution of the system of Euler equations. Three-dimensional quasi-viscous calculations - application of boundary layer theory, secondary flow and vorticity, combined vortex model, loss corrections. Calculation of spatial viscous flow in blade cascades - turbulent modeling, implicit and explicit procedures, pressure correction methods, artificial compressibility method.

numerical exercise as needed
