The Numerical Simulation of Distribution Law of Effective Temperature Field in Coal Face

摘要：

In order to let the standards of mine climate be more reasonable, this article utilizes the effective temperature which is thr ee syntheses produce of airflow velocity, temperature and relative humidity to measure the mineral environment. According to the principle of energy conservation and momentum conservation, the K-ε equation was used closed the equations. The CFD software was utilized separately carries on the value simulation to the airflow velocity field, temperature field, humidity ratio field and effective temperature field distributed map had been drawn up in coal face. The effective temperature reduces with the wind speed ascension, temperature drop, the moisture content reduces change law in mine had been obtained initially.
