VISIUN(tm) is a specialized software system for the time-dependent analysis of internal flows in turbomachinery. It employs an implicit, approximately factored finite-difference scheme to solve the 3D Euler or Navier-Stokes equations, with body-fitted grid generation, and considers flow in ducts and either stationary or rotating blade rows. The compressible flow solution is able to handle supersonic flows with shocks, as well as subsonic flows. VISIUN(tm) has been applied successfully to both radial and axial turbomachinery.
