摘　　要：为快速完成不同海拔地区沙尘天气模拟实验系统的设计需求,运用FLUENT软件对该实验系统中颗粒扩散管长的影响因素进行了数值模拟,分别对高、低风速下的模拟结果进行了无量纲分析及数据拟合。研究表明:导流器开度是控制颗粒扩散管长不至过长的重要影响因素,模拟数据拟合结果可为快速完成该实验系统的初步设计奠定基础。To design simulating experiment on sand and dust weather at different altitudes, this paper conducted numerical simulation on the influencing factors of particle diffusion tube length by FLUENT software and carried out dimensionless analysis and data fitting for the simulation results at high and low wind speeds. The results show that the opening of the diverter prevents the length of the particle diffuser from being too long. The simulated data fitting helps complete the preliminary design of the experimental system.
