Passive Augmentation Studies in a Double Pipe Heat Exchanger with Ellipsoidal DimplesBy Divya P Soman, Jomi J Nalpat, Berin Thomas, Udith Mohan
Abstract: In this work, the numerical studies of heat transfer augmentation of a counter-current double pipe heat exchanger with ellipsoidal dimples (inward-facing, raised dimples) on the inner tube was performed using SOLIDWORKS software. The effect of dimple depth, dimple pitch and number of dimples/angles between two dimples on heat transfer was investigated at a constant volumetric flow rate of 4 LPM for hot (water) and cold (water) fluids. The effect of …
