Abstract:
The influence of a counter-rotating vortical gust pair is numerically investigated on a streamlined laminar flow and forced convection heat transfer around a steadily rotating two-dimensional circular cylinder. Reynolds number is kept to a fixed value of 100 based on cylinder diameter (D). The working fluid used is water having a fixed Prandtl number of 7. The non-dimensional rotation rate is altered within the vortex shedding regime i.e. 0≤α≤1.5 in the steps of 0.25. The numerical results were computed via commercially accessible CFD software package FLUENT®. The governing flow equations are continuity, momentum, and energy equations have been resolved via constant wall temperature (CWT) boundary condition. The numerical outcomes are computed illustrating the variation in the lift coefficient, Strouhal number, average and local Nusselt number, vorticity and temperature contours around the isothermal rotating cylinder. The influence of the vortical gust is observed to stretch the shear layer in a typical manner. The vortical gust can be treated as an additional heat transfer suppression technique in conjunction with rotation for a circular cylinder.
