Heat transfer coefficient of laminar rotational flow

Abstract

Abstract A model of the distribution of laminar temperature and dynamic boundary layers is considered. An integral relation is derived for the energy equation of the temperature spatial boundary layer, that allows integration over the surface of any shape, which is necessary for determining the thickness of the energy loss., The expressions for the thickness of the energy loss of the temperature spatial boundary layer are defined for the laminar flow. The expressions for the thickness of the energy loss are necessary to determine the local heat transfer coefficients for the characteristic cases of flow, taking into account heat transfer. Analytically, expressions are obtained for determining the local heat transfer coefficient in the form of the Stanton criterion for the rotational flow according to the law of a solid and the rotational flow of a free vortex. Local heat transfer coefficients are determined for laminar rotational flows.
