چکیده

In the past, fin-and tube heat exchanger (FTHE) pattern ratios have been largely based on ad-hoc design principles. Here, we investigate optimal arrangements for a FTHE with plain fins in marine environments represented by two different air types; one unfiltered high condensation rate and clean dry filtered conditions. The thermal-hydraulic efficiency of is measured comparing modified ratio Colburn j-factor Fanning friction factor. regression model generated from CFD data then used to identify maximum specific fin pitches separately. We identified patterns: large pitch air, another small air. Manufacturing restrictions were found significantly limit achievable pattern. By neglecting related manufacturing restrictions, 4% higher 1.5 mm 23% 3.5 achieved. Without any application limitations or can 36% increased than mm. These novel results show that development potential significant improvements efficiency.

Extended Correlations for Staggered Round Tube Plain Fin Heat Exchangers

This paper develops a semi-empirical expression for heat transfer in round tube plain fin heat exchangers that have relatively large fin pitch. Empirical heat transfer correlations currently available in the public domain are necessarily limited in their range of applicability, and their functional forms are generally not designed to converge to well-known physical results, for example when par...

Investigation of Heat Transfer Coefficient Enhancement for CuO/TiO2 Nanocomposite in a Tube Heat Exchanger

In order to improve the efficiency and rate of heat transfer in heat exchangers, various techniques such as increasing the heat transfer coefficient are proposed. This study is devoted to the investigation of heat transfer coefficient variations due to the addition of CuO, TiO2 and CuO/TiO2 nanoparticles into a shell and tube heat exchanger. CuO/TiO2 nanocomposite was synthesized using mechanic...
