Heat transfer in a laminar viscous fluid flow in tubes and coaxial channels with local twisting of flow

摘要

Heat transfer in a laminar viscous fluid flow in tubes and coaxial channels with local twisting of the flow is studied. The problem was formulated in two versions - in the "vortex-stream function" form and in the Galerkin approximation. The method of finite differences and the Galerkin method are used in realization of the mathematical model.
