Numerical simulation of forced flow in boundary layer and of heat transfer by non-Newtonian fluid in view of the temperature dependence of viscosity

Differences are determined in the degree of the effect made by the temperature dependence of viscosity of fluid on heat transfer and friction. The effect of the temperature factor depends on the direction of heat flux and on the index of nonlinearity of the medium; in so doing, the rheology makes no effect on relative heat transfer and friction. The temperature dependence of viscosity of fluid is self-similar relative to the Prandtl number and makes no effect on friction. Criterional equations are obtained for the calculation of local and average values of Nusselt number and coefficients of friction under conditions of laminar forced convection in the vicinity of a cooled plate.
