Abstract
This paper describes recent developments to a three dimensional, unstructured mesh, solution-adaptive Navier-Stokes solver. By adopting a simple, pragmatic but systematic approach to mesh generation, the range of simulations which can be attempted is extended towards arbitrary geometries. The combined benefits of the approach result in a powerful analytical ability. Solutions for a wide range of flows are presented including a transonic compressor rotor, a centrifugal impellor, a steam turbine nozzle guide vane with casing extraction belt, the internal coolant passage of a radial inflow turbine and a turbine disc-cavity flow.
