Title:Including Material Cost and Strength Constraints in Heat Exchanger Design
Author(s):Davidson, I.E.; Bullard, C.W.
Subject(s):heat exchangers
heat exchanger design
Abstract:This project extends analysis of heat exchanger design tradeoffs in response to two emerging trends: 1) demands for increasing thermal performance while reducing material costs are beginning to raise structural issues; and 2) new manufacturing technologies are enabling designs that lie outside the envelope of existing empirical databases and performance correlations. Optimization methods are used to explore both conventional and unconventional designs in this broader parameter space, dealing explicitly with material- and manufacturing-related constraints. New semi-empirical correlations for heat transfer and friction factor are developed and used for analyzing flat- and round-tube plain fin heat exchangers. The role of structural constraints is illustrated by focusing on condenser optimization using a residential air conditioning model, but the analysis yields insights that applicable to other components and applications. Ways of avoiding some of these constraints are discussed in some detail.
