PROTECTIVE FILM ON THE PLATE SURFACE IN COOLING FLOW THROUGH AN INCLINED SLOTTED CHANNEL UNDER THE INFLUENCE OF A HARMONICALLY CHANGING PRESSURE

The results of numerical modeling of convective fi lm cooling of a plate in the vicinity of an inclined slotted channel with high-temperature and cooling fl ows past its two sides are presented. A fl at inclined slotted channel connects the areas of high-temperature and cooling gas fl ows. The movement of gas in both the high-temperature and cooling channels occurs under the infl uence of pressure diff erences in the inlet and outlet sections. In this case, along with the stationary component, the pressure in the cooling channel contains a component that varies according to a harmonic law. Calculations of thermal and velocity fi elds on both sides of the plate were performed, and the parameters of the cooling fi lm were described at various frequencies of pressure oscillations in the region of the cooling fl ow
