An Algorithm for Cost Comparison of Optimized Shell-and-Tube Heat Exchangers with Tube Inserts and Plain Tubes

Heat transfer enhancement is currently allocated the most part of investigations to improve the thermal performance of shell and tube heat exchangers. In this article, an algorithm for cost comparison of an optimized enhanced tube heat exchanger to an optimized plain tubes has been developed. The results are shown in plots which allow the engineers to compare directly the capital cost of heat exchangers and to select the better options among the various tube inserts for a given duty.
