Research output: Contribution to conferencePaperpeer-review


The problem of Coanda jet flow in an underexpanded supersonic environment is studied numerically by solving the Navier-Stokes equations in two and three dimensions. The study considers a flow initiated by a jet bounded by a side wall and expanding around a circular cylinder, for which a set of experimental data exists. Two different turbulence models are used in the calculation, and the results are compared with the experimental data. In the two-dimensional calculation, the characteristic oscillatory pressure pattern is reproduced fairly well. The three-dimensional calculation reveals the influence of the side wall on the overall structure of the flow field.
