Optimum Design of Heat Exchangers for Waste Heat Recovery

Abstract

A combined thermal, hydraulic and economic optimization analysis is presented yielding simple algebraic formulae for estimating the optimum operating conditions such as effectiveness and mass flow rate for three different types of heat exchangers for industrial applications. An economic analysis method is used in the present study, together with the thermal and hydraulic analyses, for thermo-hydraulic and economic optimization of heat exchangers of the three different types.
