Minimizing the Entropic Potential Losses Number in a Gasket-Plate Heat Exchanger

The entropic potential losses number shows the reduction of energy quality as a function of the entropy produced in a process. In this research, using the Harris Hawks Optimization (HHO) method, the minimization of the entropic potential losses in a gasket-plate heat exchanger has been studied. Considering six design variables: number of plates, cold inlet fluid temperature, mass flow rate of hot fluid, hot inlet fluid temperature, plate pitch, and plate width. The results showed that minimizing the entropic potential losses number increases the heat transfer rate by ۱۰۳% and the efficiency of the heat exchanger by ۲۷%. Also, the effect of some geometric and process parameters on the entropic potential loss number has also been investigated in this research. It was observed that by increasing the mass flow rate of the hot fluid in the gasket-plate heat exchanger, the entropic potential losses number will increase. It was also seen that the entropic potential loss number will also increase with the increase of hot outlet fluid temperature. It was found that with a decrease of ۲۰ degrees Kelvin in the outlet temperature of the hot fluid, the entropic potential losses number decreased by about ۰.۰۶.
