Experimental Analysis on Longitudinal Finned Tube Heat Exchanger and Numerical Investigation on Parameters that Accrue the Overall Heat Transfer CoefficientBy Pavan Kumar Konchada, Prem Dheeraj, Vinay Venkata Pragada, Purnima Sharada
Abstract: The presence of nanofluids ascertained great augmentation in heat transfer. Several works have been done so far to parameterize the properties of nanofluid in relation to augmentation of heat transfer. In conjunction to this, the present work focuses on heat transfer within a longitudinal finned tube heat exchanger with simulated employment of nanofluids. Experimentation is done on longitudinal finned tube heat exchanger and the results were compared with numerical simulations …

Optimization of Performance of Shell and Tube Heat Exchanger with Al2O3 Nanofluid as Working FluidBy Pavan Kumar Konchada, S. K. Bhatti, R. Siddhardha, K. Sanatha
Abstract: Heat exchangers are used to transfer heat between two process streams. Improving the rate of heat transfer as well as minimizing the pressure drop is one of the promising fields to focus on. Nanofluids with better thermo-physical properties can increase the heat transfer rate. In the present study, thermo-physical properties of Al2O3 nanofluid are compared with base fluid at different temperatures and the variation of heat transfer coefficient, output temperature …

Augmentation of Heat Transfer in a Trough Shaped Solar Collector Compared to Flat Plate Collector Using CFDBy Pavan Kumar Konchada, Vinay Venkata Pragada, Himagireesh Chigurupalli
Abstract: Surface Enhancement plays a vital role in augmenting the thermal performance of flat plate collectors. In this paper, an attempt is made to explain in a comparative way the effect of surface geometry of solar flat plate collector having troughs with that of a normal collector. Flat plate collectors with and without troughs of dimensions 1 × 0.5 m is modelled in CATIA V5R19 and meshed using ANSYS ICEM CFD. …
