Abstract
Numerical simulation of complex three-dimensional flow through the spiral casing has been accomplished using a finite 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 flow in high Reynolds number (106) regime. For spatial discretization, a streamline upwind Petrov Galerkin technique has been used. The velocity field and the pressure distribution inside the spiral casing corroborate the results available in literature. The flow structure reveals the fact that very strong secondary flow is evolved on the cross-stream planes.
