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方法在理論和應用方面的新成果，探索在水力計算方面的新途徑以促進lb方法實用化的發展，本文進行了下列研究工作：綜述了lb方法在理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；在水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法，它綜合了上述兩種邊界條件的優點，在流場的各種邊界處理中取得了非常好的效果，經過模塊化的處理以後這種邊界條件具有更好的實用性；針對均勻網格的lb方法計算效率較低的不足，提出了雙重網格的latticeboltzmann方法，通過二維poiseulle流動、后臺階流動和渠道方槽流動三個算例的模擬，證明這種方法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方法的分塊-耦合演算法，利用lb方法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，展示了這種演算法的特徵和優點，以及它所具有的應用前景。Only when a system po e es natural or artificial boundaries that a ociate the water within it the hydrologic cycle may the entire system properly be termed hydrogeologic
只有當一個系統擁有自然的或人工形成的邊界來把邊界中的水與水文循環聯系起來的時候，才有可能把整個的系統恰當的成為與水文地質學有關。Only when a system possesses natural or artificial boundaries that associate the water within it the hydrologic cycle may the entire system properly be termed hydrogeologic
只有當一個系統擁有自然的或人工形成的邊界來把邊界中的水與水文循環聯系起來的時候，才有可能把整個的系統恰當的成為與水文地質學有關。Compared with other general cfd software, the numerical modeling software of combustion process improved by the author of this paper has following features : ( 1 ) it can adjust the corresponding parameters and manipulating methods according to furnace architecture, operational parameters and fuels etc. ; ( 2 ) it can arrange the nodes of grid flexibly and also make special calculation to certain nodes, which cannot be accomplished by the general commercial software ; ( 3 ) in the boundary ( water - cooled wall ) condition processing, the third boundary condition is selected for the temperature calculating, linking the combustion process inside the furnace with the flow and heat exchange of water inside the water - cooled wall, so the heat absorbing and the influence of the water - cooled wall to combustion process and heat transfer of furnace are explicitly explained
與其它通用的cfd軟體相比，經論文作者所改進的燃燒過程數值模擬軟體的特點在於： （ 1 ）能夠結合爐子結構、運行參數及燃料等，調整模型中相應的參數及處理方法； （ 2 ）可以靈活的安排網格節點，對某些節點進行特殊處理； （ 3 ）在邊界（水冷壁）條件的處理上，溫度選用了第三類邊界條件，把爐內燃燒過程和水冷壁內工質的流動和換熱聯系了起來，使得水冷壁內的吸熱情況對爐內的燃燒和結渣的影響充分體現出來。分享友人
