Condensation-Induced Hydraulic Shock Laboratory Study
冷凝诱发水力冲击的实验室研究
为了了解氨制冷系统中冷凝诱导水力冲击的机理,在模拟工业装置显著特征的试验装置中进行了试验。在受控条件下进行了大量试验,不仅确定了发生液压冲击的临界条件,还确定了更严重情况下动态冲击的大小。本研究的目的是了解冷凝现象-
低温氨制冷系统受控试验环境中的诱导液压冲击。该测试程序旨在通过将热气引入带有过冷液体的管道来模拟液压冲击。ALTA Cooling,Inc.是氨制冷行业的一家经验丰富的机构,与乔治亚理工学院(Georgia Institute of Technology)成立了一家合资企业,该公司在两相流和冷凝诱导冲击方面具有专业知识,旨在研究一个具有适当规模的装置中的液压冲击,以代表大多数实际管道方案。

In order to understand the mechanisms of condensation-induced hydraulic shock in an ammonia refrigeration system experiments were conducted in a test apparatus designed to emulate salient features of an industrial installation. Numerous tests were performed under controlled conditions to ascertain not only threshold conditions for hydraulic shock to occur, but also to determine the magnitude of the dynamic shock under more severe circumstances.The objective of this research investigation is an understanding of condensation-induced hydraulic shock in a controlled test environment in a low-temperature ammonia refrigeration system. The test program was designed to simulate hydraulic shock via the introduction of hot gas into a pipe with subcooled liquid.A co-venture between ALTA Refrigeration, Inc., an experienced organization in the ammonia refrigeration industry, and Georgia Institute of Technology, with expertise in two-phase flow and condensation-induced shock, was formed to investigate hydraulic shock in an installation that is of suitable scale to represent most actual piping schemes.Units: I-P
