Abstract
A two-dimensional (2-D) injection model is developed for the discrete hole injection process. The model is incorporated in a 2-D boundary layer code using the low Reynolds number version of the k-ε model of turbulence. Predictions of spanwise averaged effectiveness and heat transfer coefficients (hf) are made. The present paper concerns itself with one row of injection into a turbulent boundary layer. The entrainment fraction is correlated to injection parameters and the p/d ratio. Predictions of velocity and temperature profiles are in good agreement with experimental data for one row of injection into a turbulent boundary layer.
