The Effects of Frost Formation in a Flat Plate Finned-Tube Heat Exchanger
نویسندگان
چکیده
An experimental study on the effects of various factors(fin spacing, fin arrangement, air temperature, air humidity, and air velocity) on the frost growth and thermal performance of a finned-tube heat exchanger has been conducted under the frosting condition. It is found that the thermal performance of a heat exchanger is closely related to the blockage ratio of air flow passage due to the frost growth. The maximum allowable blockage ratio is used to determine the criteria for the optimal operation conditions of a finned-tube heat exchanger.

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...
متن کاملMinimization of Entransy Dissipations of a Finned Shell and Tube Heat Exchanger
Improving heat transfer and performance in a radial, finned, shell and tube heat exchanger is studied in this study. According to the second law of thermodynamics, the most irreversibilities of convective heat transfer processes are due to fluid friction and heat transfer via finite temperature difference. Entransy dissipations are due to the irreversibilities of convective heat transfer. There...
