ABSTRACT

This work is devoted to theoretical investigation of heat transfer and hydrodynamics in a cylindrical tube with a coiled tape for Reynolds numbers 200-3600 and small twist pitches. A numerical solution of full Navier-Stokes and energy equations is obtained using the FLUENT applied program package. The fields of the distribution of thermodynamic parameters have been obtained. The nonstationarity of the Taylor-Goertler vortices has been revealed and, based on this, the conclusion on the possible incipience of a high-scale turbulence in swirled regions at small Reynolds numbers has been made.
