Shell and Tube Heat Exchanger Performance Analysis

A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, at different temperatures and in thermal contact. In this problem of heat transfer involved the condition where different constructional parameters are changed for getting the performance review under different condition. An excel program has been developed for the ease of calculation and obtaining result after changing different parameters. The tube diameter, tube length, shell types etc. are all standardized and are available only in certain sizes and geometry. And so the design of a shell-and-tube heat exchanger usually involves a trial and error procedure where for a certain combination of the design variables the heat transfer area is calculated and then another combination is tried to check if there is any possibility of increasing the heat transfer coefficient. Since several discrete combinations of the design configurations are possible, the designer needs an efficient strategy to quickly locate the design configuration having the minimum heat exchanger cost. In this particular problem the tube metallurgy and baffle spacing are being changed the results are obtained. In current paper the baffle spacing and tube metallurgy are the parameters considering change and effect of the same of heat transfer coefficient have been considered.
