Numerical method and code flower for calculation of 3D viscous unsteady flows within axial and radial turbomachines

The numerical method of the 3D compressible unsteady viscous flow through axial and radial turbomachine is developed. The approach is based on numerical integration of the Reynolds-averaged Navier-Stokes equations with implicit high-resolution ENO scheme. To demonstrate the power of the method the following results are presented: 3D flows through straight test cascades; 3D viscous flows in turbine and compressor (axial and radial) stages unsteady wake propagation through blade-to-blade passages of downstream row; unsteady blade cooling effects.
