THE EXTENSION OF A SOLUTION-ADAPTIVE 3-DIMENSIONAL NAVIER-STOKES SOLVER TOWARD GEOMETRIES OF ARBITRARY COMPLEXITY

This paper describes recent developments to a three-dimensional, unstr uctured mesh, solution-adaptive Navier-Stokes solver. By adopting a si mple, pragmatic but systematic approach to mesh generation, the range of simulations that can be attempted is extended toward arbitrary geom etries. The combined benefits of the approach result in a powerful ana lytical ability. Solutions for a wide range of flows are presented, in cluding a transonic compressor rotor, a centrifugal impeller, a steam turbine nozzle guide vane with casing extraction belt, the internal co olant passage of a radial inflow turbine, and a turbine disk cavity fl ow.
