Flow with heat transfer in a rotating cavity

Abstract

Abstract An integral relation of the temperature spatial boundary layer energy equation, which allows integration over the surface of any shape to determine the thickness of the energy loss, was obtained. The equations for determining the energy loss of the temperature spatial boundary layer thickness are necessary to determine the local heat transfer coefficients for the characteristic cases of flow, taking heat exchange into account. The corresponding flows in the power unit cavities are considered. Turbulent flows of a gaseous flow were considered. Calculations for local heat transfer coefficients are defined. The local heat transfer coefficient for a rectilinear flow, a rotational flow according to the law of a solid, and a rotational flow according to the law of a free vortex were determined. Calculations for local heat transfer coefficients are defined as Stanton Criteria.
