Abstract
For the high concentration dust instrumentation calibration device, it is necessary to ensure the uniformity and stability of the dust concentration distribution in the detection area. In this paper, Fluent fluid simulation software is used to numerically simulate the dust particles in the flow field, and the DPM model is used to study the transportation law of the discrete phase (dust particles) and the continuous phase (wind) in the flow field, and to determine the optimal detection area. The optimal detection area is determined by setting up dust concentration detection surfaces at different locations from the dust source and comparing the uniformity of the dust concentration distribution; the optimal transport wind speed is determined by changing the wind speed and comparing the uniformity of the dust concentration distribution while controlling the constant mass flow rate of the dust.
