Comparative Design Of Offset Strip Plate Fin Heat Exchanger For Minimum Pressure Drop Co-Efficient Using Particle Swarm Optimization Algorithm With Different Design Co-Relation

Abstract

Heat exchangers are devices that facilitate heat transfer between two fluids at different temperatures. Heat transfer
co-efficient maximization is one of the important objective for thermal design of heat exchanger. This study explores the use
of particle swam optimization (PSO) for thermodynamic design optimization of cross flow plate -fin heat exchanger.
Maximization of heat transfer co-efficient is considered as an objective function for specific heat duty requirement of late-fin
heat exchanger. Seven design variables such as heat exchanger length, fin frequency, number of fin layer, lance length of fin ,
fin height and fin thickness are considered for optimization. Design correlation proposed by Maiti-sarangi, Joshi-Webb and
Manglik-Bergles are considered for the design optimization. An application example is also presented to demonstrate the
effectiveness and accuracy of the proposed method.
