Compressed air energy storage may be an important asset for large-scale implementation of renewable energies. The REMORA technology combines quasi-isothermal compression with maritime construction efforts. Convective heat transfer in liquid piston compressors have not been thoroughly studied so far, but its understanding is deeply important to characterize the system's behavior. An experimental analysis of air compression using liquid piston is proposed for chambers with big dimensions, which leads to the development of several correlations. From these assessments, it is possible to describe the presence of two different convective heat exchange patterns, as well as the liquid piston position in the transition between them. A numerical model is developed by employing these correlations. The comparison between numerical and experimental results enables the validation of such correlations for a specific set of parameters.

压缩空气储能可能是大规模实施可再生能源的重要资产。REMORA技术将准等温压缩与海上建设工作结合在一起。到目前为止，尚未对液体活塞式压缩机中的对流传热进行彻底研究，但是对它的理解对于表征系统的行为非常重要。提出了使用液体活塞对大尺寸腔室进行空气压缩的实验分析，这导致了多种相关性的发展。从这些评估中，可以描述两种不同的对流热交换模式的存在，以及它们之间过渡处的液体活塞位置。通过利用这些相关性来开发数值模型。
