含固体颗粒流体旋流场强化传热综合性能实验
Experimental research on comprehensive performance of heat transfer enhancement of swirling flow field with solid particles
摘要
Abstract
In order to further enhance heat transfer of swirling flow field of single phase, the heat transfer experiment is conducted of liquid swirling flow field with solid particles, which researches the effect of particle concentration, particle size, Re number on comprehensive heat transfer performance in three different twisted tubes.The results show that the heat transfer performance of double phase swirling flow field increases with the rise of particle concentration, particle size and Re number.Compared with the single-phase flow field, Nu number is increased by 60.22%, 67.23% and 73.16% respectively in the three twisted tubes under the conditions of particle size 2 mm, particle concentration 1% and the same Re number.Through comprehensive performance evaluation factor analysis, the comprehensive heat transfer performance is good under the conditions of particle size 2-5 mm, particle concentration 5%, twisted tube lead 200 mm, and ellipse degree 1.49.关键词
