Fluent Based Numerical Analysis of Eliminating Ultra-Limit Gas in Upper Corner by Using Rotary Jet Fan
For the problem of gas accumulation in upper corner of "U" type ventilation system mining face, a new approach to eliminating gas accumulation in upper corner of coal mining face by using high-speed rotating jet is proposed based on flow law of rotary jet and actual environment of coal mining face. The numerical simulation with Fluent software is carried out. The results show that when fan is mounted close to the wall, the high-speed rotating jet has good Coanda effect, little impact on air flow structure of coal mining face, and is significantly effective to deal with gas accumulation in upper corner. FLUENT based numerical simulation provides a theoretical basis for actual application of rotary jet fan in coal mining face.This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.
