Abstract
Consideration is given to a developed turbulent flow in a circular tube with an infinite sequence of circumferential fins formed by equidistant diaphragms. For describing the turbulent flow, use is made of the two-parametric dissipative model of turbulence and of the wall function method. Numerical calculation of flow parameters and temperature is based on the computational procedure suggested earlier. The computational algorithm is modernized so that it allows a direct employment of Reynolds number as an input parameter rather than its determination from the predicted results, as is the case in the above-mentioned procedure. A new algorithm to solve the thermal problem is proposed. The calculated results are presented in the form of flow and temperature fields and distributed parameters over the tube surface. The influence of geometry and flow parameters on the dynamic and thermal characteristics of the flow are analyzed.
