为了分析泡沫金属在狭缝射流冲击泡沫金属强化换热的作用,在计算流体力学(CFD)的基础上,采用数值模拟的方法,对影响换热的一系列因素做了详细的研究。在模型中泡沫金属材质为纯铜,尺寸是定值,通过改变喷嘴内空气速度v、泡沫金属孔隙率φ、喷嘴宽度W与泡沫金属的高度H的比值、喷嘴到泡沫金属上表面的高度C与泡沫金属的高度H的比值,来分析各个因素对热表面换热系数、泡沫金属内温度分布和流线分布等因变量的影响。 In order to analyze the effect of foam metal on the enhanced heat transfer of foam metal by slit jet, a series of factors influencing heat transfer were studied in detail based on computational fluid dynamics (CFD) using numerical simulation. In the model, the foam metal is made of pure copper and its size is fixed. By changing the air velocity v in the nozzle, the ratio of the foam metal porosity φ, the nozzle width W and the height H of the foam metal, the height C of the nozzle to the upper surface of the foam metal And the height of foam metal H, to analyze the influence of various factors on the heat transfer coefficient, the temperature distribution in metal foam and the streamline distribution.
