首发时间:2021-10-20
摘要:超临界二氧化碳中纳米颗粒的运动沉积问题是目前的国际前沿课题。选择纳米颗粒、超临界二氧化碳作为具体对象,以水平直管作为流动几何通道,运用fluent软件采取控制单一变量法,对影响纳米颗粒热泳沉积的因素进行了计算分析。对于热泳沉积而言,流体与壁面温差是影响沉积率的最主要因素,呈正相关关系;来流速度、粒径、管径与沉积率呈负相关关系。

the nanoparticles thermophoresis deposition in supercritical co2 computing research
abstract:the motion deposition of nanoparticles in supercritical carbon dioxide is an international frontier. nano particles and supercritical carbon dioxide were selected as specific objects, and horizontal straight pipe was used as flow geometry channel. fluent software was used to control single variable method to calculate and analyze the factors affecting the deposition of nano particles in thermal swimming. the temperature difference between the fluid and the wall is the most important factor affecting the deposition rate, and there is a positive correlation. the flow velocity, particle size and pipe diameter are negatively correlated with deposition rate.
