David A. Yashar, Piotr A. Domanski, Hong H. Cho
The distribution of air flow approaching a finned-tube heat exchanger is one of the predominant factors influencing the heat exchanger’s performance. This paper describes a method for measuring and predicting the inlet air flow distribution using Particle

Evolutionary Computation Approach to Heat Exchanger Design

David A. Yashar, Janusz Wojusiak, Kenneth Kaufman, Piotr A. Domanski
The efficiency of a vapor compression system is strongly influenced by the performance of the finned-tube heat exchangers it employs. Heat exchanger performance is strongly influenced by the refrigerant circuitry, i.e., the connection sequence of the tubes

Evaporator Optimization for Non-Uniform Air Distribution

June 13, 2010
Author(s)
Piotr A. Domanski, David A. Yashar, Sunil Lee
This study demonstrates the performance improvements that can be achieved by accounting for the in-situ air flow distribution during the design phase of a heat exchanger. The heat exchanger used in this study was a two-slab, A-shaped finned-tube evaporator
