Further Information

An empirical model which simulates the effects of vane-type vortex generators in ducts was incorporated into the Wind-US Navier-Stokes computational fluid dynamics code. The model enables the effects of the vortex generators to be simulated without defining the details of the geometry within the grid, and makes it practical for researchers to evaluate multiple combinations of vortex generator arrangements. The model determines the strength of each vortex based on the generator geometry and the local flow conditions. Validation results are presented for three duct geometries containing vortex generators: a straight pipe, a transitioning S-duct diffuser, and a circular S-duct diffuser. The computations made using the vortex generator model are compared with computations made using gridded vanes as well as with experimental data.
