Experiments are carried out to investigate heat transfer enhancement from a heated square cylinder in a channel by pulsating flow. For all the experiments, the amplitude of the pulsating flow is fixed at A = 0.05. The vortex shedding frequency and the time-averaged Nusselt number are measured for various gap height (S/D = 3.5, 2.0, 1.5, 1.0 and 0.75) at Reynolds number Re = 700. The influences of...
The effects of vortex generators (VG's) on fluid flow and heat transfer have been studied extensively in the literature. The majority of these studies have examined the effects of using VG's in heat exchanger applications. Other investigations have examined the role of placing VG's in channel flow or on a heated flat plate owing to the fact that these experimental set-ups facilitate easy comparison...
