kappa-epsilon computations of flow and heat transfer in plane oblique impinging jets
Abstract
A kappa-epsilon model of turbulence was applied to obtain the solution of flow and heat transfer in an incompressible, plane, turbulent jet impinging obliquely on a flat surface. The numerical computation was for the case of alpha = 70 deg, H/D = between 30 and 50, Re between 25,000 and 120,000, and constant wall temperature boundary condition. The results of computation, including the stagnation point shift, friction coefficient, and Nusselt number, are in good agreement with available data. Algebraic equations that relate the friction coefficient and Nusselt number with Reynolds number and H/D were obtained.
