GENERALIZED METHOD FOR THE CONCEPTUAL DESIGN OF COMPACT HEAT EXCHANGERS
Paper in proceeding, 2024

The paper introduces a novel method for generalized heat exchanger design and evaluation, freeing the process from predefined geometries. It aims to facilitate early-stage conceptual exploration, allowing the designer to make informed decisions. The paper explores heat transfer and fluid friction principles in order to set key parameters for estimating aerothermal performance, introduced by LaHaye. Arguing against a single metric, the paper proposes a custom cost function for evaluating the integrated generalized heat exchanger. A case study applies the method to a particular aircraft engine scenario, using cost functions to evaluate intercooler designs based on pressure loss and heat transfer surface weight. The study determines suitable heat exchanger families for further development, considering factors like finned area, compactness and flow distribution.
