WebJul 24, 2013 · This paper proposes and implements a new methodology for optimizing Compact Heat Exchangers (CHXs) using a Volume Averaging Theory (VAT) model and a Genetic Algorithm (GA) optimizer. This method allows for multiple-parameter optimization of CHXs by design of their basic morphological structures, and is applied to a Finned-Tube … WebWhen the tube row increasing to 6, the heat transfer coefficient can be improved by about 10–20% and 9.3–25.2% for FTHXs with round and oval configurations, respectively, by increasing the fin pitch from 1.8 mm to 3.0 mm. The existing experimental correlations for wavy FTHX having round configuration fail to predict the present experimental ...
