Abstract:

Porous fence，which is an effective method to abate dust emission in a bulk material storage yard，has been used in many practical applications and aroused extensive attention in academic fields. In this paper，the current status and progress of porous fence are summarized，including mechanisms，progress of numerical simulation and several influence parameters on the shelter effect. Simultaneously，a porous fence with deflector，which plays a guiding role and directs the air flow up to a certain angle in order to reduce the direct impact on the windward surface of the bulk material pile is introduced，the shelter effect of the new porous fence is investigated numerically. The present imperfection and direction of future research are also discussed.
