Abstract
© 1988 by the American Institute of Aeronautics and Astronautics, Inc. All Rights Reserved. Numerical simulation of the outwash flow arising from the collision of two jets has been performed. First, three classical single length (or time) scale closure models, the k-ε, the Algebraic Stress and the full Reynolds Stress Transport models, were used to describe the turbulence effects. The results show that the predicted spreading rate and turbulence level are much lower than in the experiment. This observation has led to studying the flow based on a time-dependent procedure in order to capture the large-scale unsteady flow structures. The results indicate the probable importance of large-scale time-dependent flow structures in producing the additional mixing of the outwash jets.
