Description

With heat transfer enhancment techniques becoming more available, engineers must assess the effects of using a given enhancement method or selecting among several alternative methods. Trade-offs must be made between heat exchanger size, pressure drop, pumping power, flow rates, temperature differences, and heat transfer rates. Starting with the general formulation of thermal-hydraulic performance evaluation criteria for single-phase flow, a method is described for ranking several enhancement alternatives. The method is illustrated by selecting the appropriate, helical ribbed tubes for water-side heat transfer enhancement in a floodedevaporator water chiller.
