TL;DR: In this paper, the authors made an in-depth analysis of the effects of an air curtain generator's radial and axial pressure airflow rate and a dust removal fan's exhaust airflow rate on the diffusion and pollution behaviors of dust through CFD technology and field measurements.

TL;DR: In this article, the effect of air flowrate on pollutant dispersion pattern of coal dust particles at the fully mechanized mining face is investigated. And the authors aim to reduce the dust concentration through adjusting the air flow rate parameter.

TL;DR: In this paper, the effects of the air volume ratio parameters (axial-to-radial flow ratio of the wall-attached air cylinder "δ" and the forced-toexhaust ratio "β") on the air curtain dust suppression in a rock tunnel's fully-mechanized working face, the eastern belt of Huipodi mining company (Shanxi Mineral Group Co., Ltd., China) was numerically simulated by CFD software in this study.

TL;DR: In this article, the authors used computational fluid dynamics (CFD) for numerical simulation of spray nozzles with three pore diameters of 1.6, 2.0, and 2.4.

TL;DR: In this article, a highly simulated physical model of the goaf and multiple dust sources were established in order to obtain the optimal dust-removal air flow rate in the roadway, by combining the numerical simulation method, the influence of the flow rate on dust diffusion rules of the dust sources was analyzed.
