Numerical Simulation of Thermal Environment in High Heat Tunnel

Abstract:

With the increasing depth of coal mining, problems of high temperature thermal damage in mine become more and more serious. A high heat tunnel thermal environment case is numerical simulated in the presented work, PMV (Predicted Mean Vote) indices are using to predict the thermal comfort of environment, velocity field, temperature field and PMV values field in high heat tunnel had been obtained. The simulation results indicated while the inlet air velocity is 0.7 m/s, the temperatures in most tunnel area are below 26 °C and the thermal environment conforms to the Coal Mine Safety Regulation in China.
