| Abstract: | According to the principle of conservation,differential equation which can describe disturbance flow and temperature distribution law of airflow of excavation roadway is a educed. Through theoretical analysis and actual measure of flow of mine airflow and thermal process, theoretical analysis research on flow field, temperature distribution law and coupling mechanism are carried out systematically. By adopting SIMPLE arithmetic and using PHOENICS numerical simulation program, the laws elicit temperature diversification of airflow of excavation roadway reduces as a rule of negative power function with the increase of airflow speed, and increase in the proportion of linearity with the increase of temperature of entry airflow. |
