Abstract
A new hybrid scheme to calculate turbulent flows is presented here. The
scheme was first reported during the early stages of its development. In this
report, more detailed test results are presented. The scheme uses three
turbulence models of which each of them is switched on at appropriate flow
regions rather than using unnecessarily single complex model for the whole
flow region. The tests on two-dimensional transonic flows over an aerofoil
are carried out. The scheme showed no deterioration of accuracy in the
results and 30 to 40% decrease in computing time when compared with using
k-e model alone. This clearly demonstrated the significant potential for the
scheme.
