Effect of Two Inline Jetsʹ Temperature on The Turbulence They Generate Within a Crossflow

Consideration is given in the present work to the interaction of twin tandem inclined jets of variable temperature with an oncoming crossflow. This consideration is carried out numerically by means of the finite volume method and is validated by confrontation with experimental data depicted on the same geometric replica by means of the Particle Image Velocimetry (PIV). The numerical model is actually obtained by the resolution of the Navier Stokes conservation equation system by means of the turbulent Reynolds Stress Model (RSM). A non uniform grid system was applied and was particularly tightened in the vicinity of the jet nozzles in order to describe well the near field mechanisms. In this paper, we intend to focus more precisely on the exploration of the different shear stress componentsʹ behavior along the whole domain. This will give an overall idea about the established turbulence that is best way to characterize well the occurring mixing process. The latter acquires a primordial importance due to its presence in various applications and its dependence in various parameters. The efficiency of the meant applications is actually mainly equivalent to that of the mixing process itself. Since in most of the applications there is a constant need of higher temperatures, we propose here to evaluate the impact of this parameter on the generated turbulence and then on the mixing process.
