A source term model was applied to numerical simulation of a vane vortex generator

where the lift force created by a vane vortex generator was used as one part of the prototype of source term model

and a normal force was introduced as the other one.The source term depends on the shape

size and location of the vane and the freestream conditions.During numerical simulation

the vane was located on a flat plate

with its height about one fifth of the thickness of local boundary layer.The calculated results of "lift & normal force" source term model were compared under the same conditions with the calculated results and experimental data for a full gridded vane vortex generator.This source term model helps to predict the velocity and vortex fields in consistent with a full gridded vane vortex

but the grid number reduces by 65%.
