Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
This paper deals with comparisons between CFD and experiments
for a supersonic ejector. We present good results in terms
of entrainment prediction compared to home-made experimental
data for an air ejector. Over the whole range of operating conditions,
the deviation is below 10%for the k−e model. In addition,
a first attempt to tackle two-phase aspects was also performed experimentally
and by simulations.
