Analysis of the Pedestrians Influence on the Airflow Velocity Measuring in Roadway Based on CFD
To explore the cause of airflow velocity reading disorder and help the production safety of the coal mine.We select a few typical situation, using CFD software to simulate the airflow affected by pedestrian in the mine roadway, revealed the distributive characteristic of airflow velocity in different situation, analyzed the range of the pedestrians influence on the airflow velocity measuring.Concluded that; because of the persons exist there will be a velocity disorder region behind the person.The velocity will be slow down in his behind but it will be increase in his side of rear. The oscillation will attenuate slowly if we let it grow freely.The result provides some reference for coal mine airflow velocity measuring.
