Simulation in Heat Transfer Enhancement of Compact Heat Exchanger using Aluminum Oxide(Al2O3) and Magnesium Oxide (MgO) using CFD

In this present work, the cross flow heat exchanger (CFHE) is utilized and computational fluid dynamics (CFD) is used to analyze the performance of evaporator to enhance the thermal efficiency, and to improve the distribution of fluid flow. CFHE has a capacity of providing 1.5 m3 /min of water at 55°C for a Combined Heat & around 200°C for the nano fluids. The CFD principles utilized in this effort are effective and suitable techniques that use finite elements to solve the heat exchanger processes. The required finite element computations are done by Ansys software tool and the obtained outputs are shown in graphical representation. This analysis is accomplished for this heat exchanger under the required conditions of inlet flow to the evaporator, and finally the comparison and conclusion are presented.
