Abstract

This is an experimental analysis; here we use different Roughness in parallel flow heat exchanger for the heat transfer enhancement at same pump power. Mass flow rate is control by using valve from 0.1 to 0.6 kg/s. The present work is based on the heat transfer augmentation technique. In the present work an experimental and numerical analysis of augmentation of laminar and turbulent flow in horizontal concentric pipe in parallel flow heat exchanger with inserts pipe of different pitch to rib height ratio (P⁄e) varies from 5-15 respectively. water is to be acted as working fluid here. This experiment is done by taking Reynolds number range from 3000-20000 regimes. Using different pitch for breaking laminar sub layer and increasing turbulence and heat transfer rate with increasing Reynolds number. In the ribbed pipe showed that longitudinal swirl flow were generated inside the pipe. By using this roughness in pipe we find that The maximum enhancement in Nusselt number is found to be 3.12 and that of friction factor is obtained to be 2.59 corresponding to (P/e) of 10.The maximum value of Thermal hydraulic performance for (P/e) 10 is varies from 1.5-2.25.
