Analysis of flow in the spiral casing using a streamline upwind Petrov Galerkin method

Numerical simulation of complex three-dimensional ow through the spiral casing has been accomplished using a nite element method. An explicit Eulerian velocity correction scheme has been deployed to solve the Reynolds average Navier{Stokes equations. The simulation has been performed to describe the ow in high Reynolds number (106) regime. For spatial discretization, a streamline upwind Petrov Galerkin technique has been used. The velocity eld and the pressure distribution inside the spiral casing corroborate the results available in literature. The ow structure reveals the fact that very strong secondary ow is evolved on the cross-stream planes.
