Heat Exchange During Rotational Motion of Liquid Above the Immobile Plane

The boundary layer heat exchange is studied for the high-temperature vortex flow above the immobile plane with the arbitrary profile of circular velocity. The mathematical simulation is conducted on the basis of nonlinear differential equations of motion (Navie-Stokes) and energy transfer (Fourier-Ostrogradskii).The effect of value decrease for the heat flow density and heat transfer factor has been confirmed experimentally. The possibility to control the gas screen (and in so doing, the heat exchange process) is revealed. The heat exchange in the diesel combustion is given for an example. The "internal adiabatization" property, inherent to the rotational flow, is considered as a means of thermal protection of the heat-sensing surface of the combustion against thermal loads.
