出口压力对煤矿主风机风门温度场的影响
Influence of outlet pressure on temperature field of ventilation door of main fan in coal mines
摘要
Abstract
This paper is aimed at exploring the influence of outlet pressure on the temperature field of ventilation door of main fan in coal mine.The study measures the temperature of some point in air duct and the initial value in coal mine through experiment and simulates branch duct multi-field coupled heat transfer under different outlet pressure using the fluid dynamics analysis software Fluent.The work shows that the experiment and simulation results have a consistent change trend,with a maximum error of 8.9％.The research on low temperature region,low temperature position,numerical centerline temperature,and horizontal centerline temperature under different outlet pressure shows that outlet pressure has significant influence on ventilation door temperature;in the case of the small outlet pressure,the low temperature region occurs only on upper part of ventilation door,and mostly in middle part and the temperature field distribution has asymmetric characteristics;the increased pressure allows low temperature region to diffuse to the left half,particularly to the lower left half of ventilation door;and the high temperature region is generally concentrated in the edge of ventilation door.The study could provide some references for prevention and control freeze damages of ventilation door of main fan in coal mine.关键词
