Abstract

A mathematical model of flowing and heat trasferring was modeled to simulate the distribution of the temperature field of the air in high temperature and high humidity caving face in mine. Two equation turbulent model was used to close the basic governing equations. And the standard wall-function was used to correlate physical quantities near the wall and in the turbulence core area. The distribution of temperature was calculated by SIMPLE algorithm. And the simulation result was compared with the data measured in the caving face. Then the refrigeration effects of different air conditioning schemes were simulated, and the distribution of temperature field of them were analysed. Theoretical instructions were supplied for the refrigeration scheme designing in mine.
