The work undertaken as part of projet magister is a numerical by programing in FORTRAN, a jet axisymetric turbulent and stationary impinging perpendicaly a circular flat plat with heat transfer. This configuration allows cooling or heating locally a surface.
The systeme of equations governing the phenomeon is solved using a computer program based on the finite volume method. The effect of turbulence were taken into account using the the stendard k-ε model.
It was conducted a characterization of different parts of impinging jets including a free jet region, a stagnation region and a wall region jet. A change in dynamic and thermal behavior has been demonstrated through the fields of average velocity, turbulent kinetic energy, pressure and temperature. The effects of Reynolds number and distance nozzle-wall impact on the flow have been explored.
