Resumo

3D Navier-Stokes calculations have been performed on a fixed geometry in presence of discrete-hole injections. Wall streamlines, constant temperature contours and temperature profiles in the interaction region are presented for one blowing rate value (R = 0.6). The quality of the flow is assessed by experiment results. Calculation code was developed to solve the steady state of three-dimensional Navier-Stokes equations, coupled with a k-ε turbulence model, using a finite volume technique. Calculations are performed on a row of hot jets inclined in a flat plate turbulent boundary layer of a compressible flow (M = 0.72). A reasonable agreement with measurements was achieved for the flow field. The temperature profiles and the lateral temperature spreading are compared with those of experimental data. The over and the under predictions are shown by the turbulence model.
