HEAT EXCHANGE IN TURBULENT FLOW OF AN INCOMPRESSIBLE LIQUID IN A ROUGH TUBE WITH A CONSTANT WALL TEMPERATURE
V. A. Babkin UDC 536.244 Turbulent flow of an incompressible liquid in a tube is considered as flow of an oriented liquid whose symmetry is determined by the director. The velocity profile and the temperature field in steady-state flow in a straight circular tube with a rough wall are determined within the framework of the model. The solutions found coincide with analogous solutions for a smooth tube for roughness equal to zero.
