Abstract
Heat exchange in a viscoplastic liquid moving in a circular pipe is investigated, taking into account the dependence of plastic viscosity and ultimate shear stress on temperature. A system of motion, energy, and continuity equations transformed under the assumption that the Pe and Pr numbers are much greater than 1 is solved on a computer by the method of finite differences using iterations. Results of the numerical solutions for the exponential form of the dependences of the rheological characteristics on temperature are analyzed in detail. A comparison of the numerical solutions with well-known theoretical solutions in particular cases and also with experimental data indicates their high precision.
