Thermo Hydraulic and Economic Optimization of Double Pipe Heat Exchangers

Murtaza YILDIRIM, Mehmet Sait Söylemez


A multi variable thermo economic and hydraulic optimization analysis is presented yielding simple algebraic formula for estimating the optimum area of counter flow tubular heat exchangers of both fluids unmixed type which are applied in industrial applications. An economic analysis method is used in the present study, together with the thermal and fluidic analyses of such heat exchangers, for thermal, economic and hydraulic optimization. The validity of the optimization formulations was checked with realistic applications.
