  1. In recent years, plentiful and substantial fruits achieved by the lb method in simulations of hydraulics, multiphase flows, flows in porous media and heat transfer as well as magnetohydrodynamics, have revealed a broad perspective of application of this method, it will become a powerful competitor to the conventional approaches. in order to absorb the recent achievement in theory and application of the lb method, explore new ways in hydraulic computation to promote the development of practice, some work is car ried out in this thesis, as following : advances in the theory research and application, deductive process of the d2q9 model and some other commonly used models of the lb method are summarized. based on the hydrodynamic and general boundary conditions, a new joint boundary condition is presented, it integrates advantage of the two conditions above and obtains very good results in dealing with all kinds of boundaries of flow fields

    為了消化和吸收近年來lb方論和應用方面的新成果,探索在力計算方面的新途徑以促進lb方實用化的發展,本文進行了下列研究工作:綜述了lb方論研究和實際應用方面的新進展,以及d2q9模型的推導過程和其他一些常用的模型;在動力邊界條件和通用邊界條件的基礎上提出了一種新的聯合邊界條件方,它綜合了上述兩種邊界條件的優點,在流場的各種邊界中取得了常好的效果,經過模塊化的以後這種邊界條件具有更好的實用性;針對均勻網格的lb方計算效率較低的不足,提出了雙重網格的latticeboltzmann方,通過二維poiseulle流動、臺階流動和渠道方槽流動三個算例的模擬,證明這種方能夠明顯地提高流場模擬的計算效率;此外,根據復雜區域流場的特徵提出了latticeboltzmann方的分塊-耦合演算,利用lb方的計算特性實現塊與塊之間的數據交換,充分利用計算資源提高計算效率,通過對「 t 」型、 「十」型和「 x 」型分岔管道流場的模擬,展示了這種演算的特徵和優點,以及它所具有的應用前景。
