Abstract:

The present study addresses the development and implementation of computational procedures for analysis and prediction of flows in centrifugal impellers. Two approaches have been investigated a solution of the Navier-Stokes equations, and b solution of an approximate set of viscous primary secondary flow equations by an efficient spatial marching algorithm. Solution of the Navier-Stokes equations has been directed towards computing the flow field in a rotating centrifugal impeller passage. Computed results show all the flow features of measurements. The spatial marching approach has been directed towards derivation of approximate flow equations and development of an efficient solution algorithm suitable for computing impeller flow fields. Flow in a rotating 90-degree bend was used as a test case for the spatial marching approach. Computer results for the rotating duct show characteristic features of impeller flow fields
