“…Masoud Asadi, Ramin Haghighi Khoshkhoo (2014) [7] had demonstrated effect of chevron angle on heat transfer coefficient, friction factor and pressure drop of corrugated PHE. From this study it was concluded that, optimal value of cheveron angle is 60° and friction factor varies inversely with mass flow rate of both fluids in laminar and turbulent zone.…”

Heat exchangers are devices that provide the exchange of heat between two same or distinguished fluids that are at different temperature without mixing them with each other. Plate heat exchanger is one such compact heat exchanger, provides more heat transfer between two fluids in comparison with shell and tube heat exchanger. This study is focused on use of corrugated plate heat exchanger (PHE) for water as a working fluid. This research work deals with experimental investigation of corrugated type of PHE with evaluation of convective heat transfer coefficient, overall heat transfer coefficient and exchanger effectiveness. Heat exchanger for carrying out this work consists of thin metal brazed plates of stainless steel with 0.5mm thickness, plates with rectangular geometry and corrugations on plate surface with chevron angle 45 0 /45 0 , plate spacing of 2.24mm and with 14 number of plates. Tests are conducted by varying operating parameters like mass flow rate of hot water, inlet temperatures of hot water. The main objective of this work is to find out effects of these parameters on performance of heat exchangers with parallel and counter flow arrangements. Results show that convective heat transfer coefficient increases with increase in mass flow rate and Reynolds number. Also the effectiveness varies with the mass flow rate of hot water. In this study, maximum effectiveness achieved for parallel flow arrangement with water as a working fluid is 0.67 and that of counter flow arrangement is 0.82. Use of plate heat exchanger is more advantageous than the tube type heat exchanger with same effectiveness as it occupies less space.

Purpose The study aims to use nanofluids as coolants for improving heat transfer peculiarities of plate heat exchangers (PHE). The experimental and numerical investigations are thoroughly performed using distilled water-based Al2O3, graphene nanoplatelet (GnP) and multi-walled carbon nanotubes (MWCNT) nanofluids. Design/methodology/approach The numerical simulation based on Single Phase Model (SPM) was performed on a realistic 3 D model of PHE having similar dimensions as of the actual plate. The standard k-epsilon turbulent model was used to solve the problem. The concentration and flow rate of nanofluids were ranging from 0.1 to 1 Vol.% and 1 to 5 lpm, respectively, at 30°C. Whereas, hot side fluid is distilled water at 2 lpm and 80°C. The heat transfer characteristics such as bulk cold outlet temperature, heat transfer rate (HTR), heat transfer coefficient (HTC), Nusselt number (Nu), pressure drop, pumping power, effectiveness and exergy loss were experimentally evaluated using nanofluids in a PHE. Findings The experimental results were then compared with the numerical model. The experimental results revealed maximum enhancement in an average heat transfer rate of 9.86, 14.86 and 17.27% using Al2O3, GnP and MWCNT nanofluids, respectively, at 1 Vol.%. The present computational fluid dynamics model accurately predicts HTR, and the results deviate <1.1% with experiments for all the cases. The temperature and flow distribution show promising results using nanofluids. Originality/value The study helps to visualise heat transfer and flow distribution in PHE using different nanofluids under different operating conditions.
