Calculations of 3D Impinging Jets in Crossflow with Reynolds Stress Models
ABSTRACT
The roles of the turbulent diffusion model and the pressure-strain model in calculations of three-dimensional impinging jet in crossflow are investigated. Computations are performed for two jets of equal strength issuing from pipes on opposite sides of a channel into an ambient crossflow which impinge on each other near the center. A multigrid procedure is utilized to accelerate convergence. Two turbulent diffusion models and two pressure-strain models are utilized. The results show little influence of the turbulent diffusion models on the mean flow but greater effect on the Reynolds stresses. The pressure-strain models show somewhat greater effects on the mean flow and Reynolds stresses.
