“…on the tube with a vortex generator insert and results obtained using CFD software. The numerical values of the present study are closely matches with the experimental values reported by P. W. Deshmukh [1] et al In the graph on Y-axis ratio of Nusselt number for an augmented case with the smooth pipe case is taken. It is found that the vortex generator with e/d ratio=0.09, α=15° and for all the three p/pl ratios has the lowest Nusselt number enhancement.…”

“…The device used in the present study is a modified version of the insert proposed by Deshmukh and Vedula [10]. The major difference being that the curved delta wing is made to extend from the wall to the centre of the tube which is necessary since the thermal boundary layer extends all the way to the centre of the tube in laminar flow.…”

“…They found that the enhancement of the Nusselt number and friction loss are around 2 -25% and 4 -30%, respectively. Deshmukh and Vedula (2014) reported the influences of the projected length ratio, height to tube inner diameter ratio and flow attack angle of curved delta wing vortex generators inserted in a circular tube heat exchanger on thermal performance. They claimed that the Nusselt number for the tube heat exchanger with vortex generators is around 1.3 -5.0 times higher than the smooth tube with no vortex generators.…”
