Analysis of the effects of rotation on an axisymmetric wall Jet

Abstract : The case of a turbulent round jet impinging perpendicularly onto a rotating, heated disc is investigated, aiming at understanding the mechanisms at the origin of the influence of rotation on the radial wall jet and associated heat transfer. The present study is based on the complementary use of an analysis of the order of magnitudes of the terms of the mean momentum and Reynolds stress transport equations, available experiments and dedicated Reynolds-Averaged Navier–Stokes (RANS) computations with refined turbulence models. The analysis identifies a scenario for the appearance of rotational effects when the rotation rate is gradually increased.
