A numerical simulation of a previous wind tunnel experiment on an impinging jet
in a crossflow was conducted.
This study compared the results of the two-
equation k-£ turbulence model with those obtained with the one-equation
Baldwin-Earth and the zero-equation Baldwin-Lomax turbulence model.
the Cp distribution along the ground level of the symmetry plane, it was shown
that among the three turbulence models tested, the flow field of the ground vortex
and its location were best simulated by the k-£ turbulence model.
Lower C% and
QC coefficients in the k-e model yielded best results for the vortex location, but
did not accurately capture the ground vortex strength represented by Cpmm The
one-equation Baldwin-Earth turbulence model gave a poor prediction of the
ground vortex behavior, and...
