布水器性能测试平台设计及应用

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.

Design and Application of the Diffuser Performance Test Platform

The diffuser performance test platform and its temperature measurement system has been designed and installed for the optimization design on diffuser and its performance parameters research. This platform can be used for analyze the thermocline under different parameters or different type of the diffuser. According to the simulation, calculation results and some experimentals, the radial diffuser with a high Reynolds number can get a good thermocline; the thermocline of the octagonal diffuser is better than radial diffuser under the same outlet flow and a certain tolerance; the thermocline of the radial diffuser is better than octagonal diffuser under the same Reynolds number.
