Investigation of the ventilation simulation model in mine based on multiphase flow

A three-dimensional mathematical model of the working face in mine was set up by using computational fluid dynamics, and the moving and heat exchange of the multiphase flow in ventilation pipeline in mine was simulated. The distribution of the wall temperature was simplified, and the gas and grain are included in this paper. The coupling effect between the phases were considered in this model to reflect their relations. The changing of one phase according to the other one can be stated. The distribution of the temperature of the air without vapor and that of multiphase flow were compared. An effective tool for simulating the system of ventilation in mine and efficient running of it were stated.
