Fullcoverage filmcooling  A oneequation model of turbulence for the calculation of the fullcoverage and the recoveryregion hydrodynamics
Abstract
A oneequation model of turbulence has been constructed in order to compute the fullcoverage recovery region hydrodynamics of a filmcooled surface. The model incorporates a detailed description of the form and dynamics of the mixing length profile of the surface, based on extensive experimental data and a physical interpretation of some simple flow calculations. The numerical calculations were performed using a twodimensional finite difference boundary layer code giving predictions of the spanwise averaged mean velocity and turbulent kinetic energy profiles between injection rows in the full recovery region. The mean velocity profiles corresponding to an injection velocity of 0.9 Mach are given in a table.
