摘要:
利用计算流体力学和数值传热学的方法,采用非一致网格,应用Fluent软件对3种型号微肋管管内的单相流动与传热性能进行了三维数值模拟计算和理论分析,研究了管内流体的雷诺数及管子几何尺寸对其流动与传热性能的影响,其计算结果与实验结果基本吻合.结果表明:当10 000<Re<120 000时,与圆管相比,微肋管的努塞尔数分别达到了光滑圆管的1.88、2.08和2.48倍,而阻力系数为光滑圆管的1.60、1.68和1.72倍.
Abstract:
The three-dimensional numerical simulation and theoretical analysis on the onephase flow and heat transfer performance in three kinds of microfin tubes were done with nonuniform grid and the software Fluent for computing fluid dynamics and numerical heat transfer. The effect of Reynolds number and the microfin tube size on the flow and heat transfer properties were studied. The results are basically consistent with the experimental data. The results show that, when 10000<Re<120000, compared with smooth tube, the Nu  numbers of the microfin tubes are 1.88 times, 2.08 times and 2.48 times of that of smooth tube, respectively, while the friction coefficients of the microfin tubes are 1.60 times, 1.68 times and 1.72 times of that of smooth tube, respectively.
