基于Fluent的旋转射流风机消除上隅角瓦斯超限数值分析
Numerical Analysis of Eliminating Gas Accumulation at Upper Corner by High-velocity Rotary-jet Fan Using Fluent
摘要
Abstract
Based on the characteristics of the working face of a U type ventilation system and the rotational flow rules,this paper proposes a new method for eliminating the gas accumulation at the upper corner of the working face with the high-velocity rotary-jet fan.It uses the fluid computation software Fluent to simulate and analyze the three positions in the same section where the rotary-jet fan is placed.The simulation results show that this method is effective for eliminating the gas accumulation.They also show that the three positions where the rotary-jet fan is placed have different effects on the main wind flow and on eliminating the gas accumulation at the upper corner,being the most effective when the rotary-jet fan is placed in the central section of a ventilation lane and when the rotary-jet fan is placed at the angle between the gob and the top board.关键词
