Turbulence Models for Computations of 3D Turbulence jet in Crossflow

B. Bounegta, R. Dizene, M. Abdelkarim and M.A. Maazouzi

Abstract:
A turbulence models with the thermal effect of jets issuing into an incompressible hot cross at an angle over a turbine blade is the subject. Numerical solutions for two holes spacing and same jet issuing angles document strong to moderate secondary vortex structures spanning normal to direction of the jet. This fully three-dimensional flow field strongly influences the cooling performance of the hole-blade system. Turbulence closure is achieved with the realizable k-ε model. The realizable k-ε models yield reasonable agreement for the mean flow velocity and better predictions.
