由于需要优化设计布水器,对其性能参数进行了深入研究,设计安装了布水器性能测试平台及测温系统.该平台可用于对比分析不同参数、不同类型布水器的斜温层效果,通过相关模拟计算及实验,初步得出相同出口流速的径向型布水器在大雷诺数也可以取得较好的斜温层效果,另外,在相同出口流速及一定的容忍度下,八角形布水器的斜温层效果优于径向型,而在相同雷诺数下,径向型布水器的分层效果优于八角形布水器.
Due to the need to optimize the design of water distributor, the performance parameters of the water distributor have been deeply studied, and the water distributor performance testing platform and temperature measurement system have been designed and installed.The platform can be used to compare and analyze the temperature difference effect of different types of water distributor Through the relevant simulation calculation and experiment, the radial water distributor with the same outlet velocity can obtain better temperature-dependent layer effect at large Reynolds number. In addition, under the same outlet flow rate and certain tolerance, The effect of temperature distribution of the angle water distributor is better than that of the radial type. However, under the same Reynolds number, the radial water distributor has better delamination effect than the octagonal water distributor.
