A Turbulence Model for Recirculating Flow

by admin @ Thursday, June 4th, 2009. Filed under Mechanical engineering, civil engineering

File : pdf, 1 MB, 30 pages
Abstract
A simple adjustment is proposed that improves the predictions of the standard k-E turbulence model in the presence of two-dimensional recirculating flow. An eddy Reynolds number calculated from velocity, vorticity, and eddy viscosity is introduced as a scaling parameter for reducing the decay term in
the governing equation for the [...]
