Research on Sand-Blocking Mechanism of Fence Based on CFD Technology

The airflow field and sand movement path around fences of 0 and 40% porosity are of numerical calculation by CFD technology and the sand-blocking mechanism of fence is analyzed comprehensively. The results show that the two preconditions for the good sand-blocking performance of fence are to greatly reduce the coming wind velocity and form a large weak wind velocity area, and ensure the sand movement path in the weak wind velocity area. The numerical simulation research of the sand-blocking mechanism of fence is an useful supplement of traditional experimental research and of reference significance in further understanding the dynamic mechanism of fence protection.
