水基铜纳米流体管内颗粒凝并的数值模拟研究
Numerical simulation of Cu/water nanofluid particles coagulation in pipes
摘要
Abstract
In this paper , the motion , particle diffusion and coagulation of the Cu/water nanofluid in 3D horizontal circular tube are simulated by using the LES model and the Taylor expansion moment method .The evolution of nanoparticles in the tube was studied .The results show that the particle size increases and the density decreases with the particle coagulation .The mixing of the small particles ,the particle coagulation and the particle size are changed at the same time ,which leads to the distribution of the parabola in the radial direction .The larger the flow field Reynolds number is ,the stronger the inhibition of coagulation .关键词
