Influence of Ocean Conditions on Heat and Mass Transfer Performance of Heat Exchangers: A Review

The research reviews the study on the thermo-mass transfer performance of heat exchangers under sloshing conditions in marine environments, aiming to promote the efficient utilization of new energy sources. It discusses the progress in the study of heat exchangers under different sloshing conditions, including theoretical models and comparisons of various swaying conditions, and comprehensively reviews the key factors influencing the enhancement or deterioration of heat transfer in heat exchangers. The research indicates that increasing the swing amplitude of spiral tube heat exchangers, reducing the swaying period, and other methods can enhance heat transfer; conversely, increasing the rolling amplitude of coil heat exchangers, extending the pitch period, and similar actions can weaken heat transfer. The mass flow rate of the working medium, steam quality, and the parameters of the sloshing motion affect the uniformity of medium distribution. When the sloshing factor is introduced, the correlation of heat transfer is highly related to the range of dimensionless numbers (such as Re and Pr) and the physical dimensions of the heat exchanger. Additionally, the article discusses techniques to mitigate the negative effects of swaying and improve heat transfer performance through improved distribution methods. Overall, the article provides significant insights into understanding the thermo-mass transfer performance of heat exchangers in marine environments, offering valuable references for engineers and researchers in related fields.
