Full Analysis of Low Finned Tube Heat Exchangers
In this paper, first the governing parameters characterizing low-finned tubes are reviewed. Second, the more important of the available performance correlations are compared with the available experimental data. The most reliable one can be employed to develop a pressure drop relationship, which has already been used in an algorithm for exchanger sizing. Also a means for the identification of a...
متن کاملNumerical Studies on the Performance of Finned-Tube Heat Exchanger
Finned-tube heat exchangers are predominantly used in space conditioning systems, as well as other applications requiring heat exchange between two fluids. The design of finned-tube heat exchangers requires the selection of over a dozen design parameters by the designer such as tube pitch, tube diameter, tube thickness, etc... Finned-tube heat exchangers are common devices; however, their perfo...
متن کاملFriction Loss and Heat Transfer Coefficient in Finned Tube Heat Exchangers for Reheating Massecuites
Equations developed for packed columns may be used to predict the overall heat transfer coefficient and friction loss in massecuite reheaters. The results seem to indicate that exchangers with the tubes staggered give higher heat transfer rates than those with the tubes in line.
متن کاملApplication of ZnO/TiO2 Nanocomposite for the Improvement of Heat Transfer Coefficient in Tube Heat Exchangers
The potential of nanofluids for the improvement of heat transfer coefficient in various heat exchangeequipment has been considered and studied as a major application during recent decades. In this research,heat transfer coefficient of ZnO, TiO2 and ZnO/TiO2 nanofluids in a shell and tube heat exchanger has beenstudied experimentally. ZnO nanoparticle was synthesized through pre...
متن کاملOptimization of Finned-Tube Heat Exchanger with Minimizing the Entropy Production rate
A compact fin-tube heat exchanger is used to transfer current fluid heat inside the tubes into the air outside. In this study, entropy production and optimized Reynolds number for finned-tube heat exchangers based on the minimum entropy production have been investigated. As a result, the total entropy of compact heat exchangers, which is the summation of the production rate of fluid entropy ins...
