Abstract

In this paper, we present a review of the recent progresses in spray impingement heat transfer mechanisms and influences of various controlling parameters on spray impingement cooling performance. This paper focuses on the developments in spray cooling effectiveness achieved by modifying the flow processes and parameters. The open literature reveals that spray impingement cooling processes studies explore practical applications but not full understanding that can help to further improvement. There are many possibilities of improving the performance of spray cooling by alternating the fluid types, flow pattern and controlling parameters such as air/water pressure and to distance from nozzle to heated plate. Some of the earlier researchers have also tried pulsed spray impingement technique to enhance the heat transfer effectiveness during metal surface cooling. However, there remains a need for further examination and the present review discusses several such possibilities.

金属表面喷雾冲击冷却：进展机制综述

摘要

在本文中，我们综述了喷雾冲击传热机制的最新进展以及各种控制参数对喷雾冲击冷却性能的影响。本文重点介绍通过修改流动过程和参数而实现的喷雾冷却效果的发展。公开文献表明，喷雾冲击冷却过程研究探索了实际应用，但没有充分理解有助于进一步改进。通过改变流体类型、流动模式和控制空气/水压等参数以及喷嘴到加热板的距离，可以有多种提高喷雾冷却性能的方法。一些早期的研究人员也尝试过脉冲喷射冲击技术来增强金属表面冷却过程中的传热效率。然而，仍然需要进一步审查，本次审查讨论了几种此类可能性。
