PLATE HEAT EXCHANGERS: AN INVESTIGATIVE STUDY

Abstract

A gasket plate heat exchanger is a vital heat recovery equipment that exchanges heat from high to low fluid Temperature with the help of corrugation plates. The heat exchanger plates provide a large surface area for heat transfer per unit volume. So now days play an important part in industrialized society, as energy demands rise, and its performance must increment as well. They have been widely used in various industrial applications, including chemical, chilling water and dairy. In the present work, the thermal modeling and optimal solution design of the gasket plate heat exchanger have been presented. For the numerical simulation and range of operating parameters and geometrical have been considered. for performance of the gasket plate heat exchanger has been studied in terms of effectiveness, heat transfer and pressure drop for both fluids. Correlations have been developed to calculate the heat transfer, effectiveness and friction coefficients using the analysis regression process. The next step has been optimized for the single objective and multi-objective functions, applying genetic algorithm optimisation “MATLAB TOOLS OPTIMIZATION.” This work aims to minimize the entropy generation units (Ns) and annual cost (TAC) for two independent objective functions. The results of optimized designs have been solved after generations for two objectives, single objective and multi-objective Optimization. The optimum solutions decision has been compared for constraint heat transfer and unconstrained optimisation.
