Designing and dust control performance of internal and external dual swirl air curtain in fully mechanized excavation face

In response to the problem of excessive dust concentration at the coal mine heading face, a new type of internal and external dual swirl air curtain generator was designed. Numerical simulations and similar tests were carried out to investigate the characteristics of the wind flow field and the dust...
