在边界层风洞中模拟了防风网附近的湍流流动,应用子波分析对防风网泄流的湍流信号进行了研究,发现与无防风网平坦条件相比,湍涡的能量及发生的频率都有显著降低.这说明,防风网在降低风速的同时也降低了湍涡发生频率,起到抑制起尘的作用.

Chen YQ, Yao ZH, Zheng XP. 3-D numerical simulation of fracture processes in heterogeneous brittle materials. Acta Mechanica Solida Sinica. 2002;15:332-341.Abstract
By using the lattice model combined with finite element methods and statistical techniques, a numerical approach is developed to establish mechanical models of three-dimensional heterogeneous brittle materials. A special numerical code is introduced, in which a lattice model and statistical approaches are used to simulate the initial heterogeneity of material properties. The size of displacement-load step is adaptively determined so that only few elements would fail in each load step. When the tensile principal strain in an element exceeds the ultimate strain of this element, the element is considered broken and its Young's modulus is set to be very low. Some important behaviors of heterogeneous brittle materials are indicated using this code. Load-displacement curves and figures of three-dimensional fracture patterns are also numerically obtained, which are similar to those observed in laboratory tests.
