VISIUN-2FR is a specialized software system for the two-frame-of-reference analysis of internal flows in turbomachinery. It employs an implicit, approximately factored finite-difference scheme to solve the 3-D Euler or Navier-Stokes equations, with body-fitted grid generation, and considers flow in ducts, and both stationary and rotating blade rows. The compressible flow solution is able to handle supersonic flows with shocks, as well as subsonic flows. VISIUN-2FR has been applied successfully to both radial and axial turbomachinery. Its processor allows the designer to quickly create a finite-difference grid, a complete set of boundary conditions, and an initial flowfield. Tracking and steering minimize convergence time for a solution. The postprocessor provides important plots including blade loading diagrams. It also supports powerful flow visualizers.
