Numerical Simulation of the Cooling Effect by Air Conditioner and Spraying in High-Temperature Working Face
A multicomponent turbulent model of the airflow in working face was modeled.And the simulation result is compared with the measured temperature.The temperature of the airflow along the transportation channel of working face goes up,and the gradient of the temperature curve is flat.Then the low-temperature droplets are simulated by stochastic separated flow model.The interaction between grains and fluid are simulated by adding source terms in conservation equations.The temperature curves of the airflow under different cooling schemes are investigated.If the air conditioner is in front of the nozzles,the temperature of the air near the inlet is low and uniform,and the cooling effect of the outlet is obvious.
