CFD numerical simulation on internal air flow field of coal mine refuge capsule
Abstract：3d model is built by using the k-ε turbulence model,the numerical computer simulations of the air distribution inside of coal mine refuge capsule is carried out with the computational fluid dynamics(CFD).The result shows that the mean temperature is 29 ℃,when the temperature is 22 ℃ and the wind rate of the outlet airflow for the refrigeration equipment is 3 m/s.The result satisfies the design requirement of temperature in the coal mine refuge capsule and it is approximately same with the test results.The conclusion provides a reference for subsequent research on a suitable air supply condition,and for the optimization of internal space in the coal mine refuge capsule.
