Abstract
The compression ramp flow, test cases TC4 in the ETMA Workshop, have been computed with two different Explicit Algebraic Reynolds Stress Models, EARSM, together with Chien low Reynolds number k-ε model. The effect of the Sarkar compressibility correction of the dissipation has also been studied. The goal of this work is to investigate the possibilities and limitations of the Explicit Algebraic Reynolds Stress Models for this kind of separated flow.
The solutions are, however, not grid independent and one has to be very cautious when drawing any further conclusions from the study of the comparison between computations and experiments. The trends are, however, quite clear and show that the EARSM models gave a much larger separated region and also that the Sarkar compressibility correction of the dissipation gave a slightly larger separation.
The EARSM extension of the k-ε turbulence model did not introduce any further numerical problems and the difference in computational effort to reach steady state was negligible.
