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。Comprehensive hybrid variety
綜合雜交品種Seventy - nine improved wheat cultivars ( lines ) including some related parents were corssed with rye to detect the difference of crossability among wheat genotypes and the developing tendency of crossability during the cultivar renewing period in shandong province, the results expressed that crossability of improved cultivars with rye were significantly lower than that of the check ( chinese spring ), and there were 3 cultivars with a seedset of more than 50 %, 4 cultivars with the seed - set of 30 % - 50 %, 8 ones with that of 10 % - 30 %, 50 ones with the seed - set of less than 5 %, and the other 14 cultivars with the seed - set of 5 % - 10 % ; the mean crossability between wheat and rye decreased with the renewing of cultivars in shandong, and the number of cultivars with the seed - set of more than 50 % and 30 % - 50 % also decreased, but that with the seed - set of less than 5 % increased gradually during the renewing period ; pedigree analysis revealed that the crossable gene of the tested cultivars might come from 3 landraces ( youzimai, mazhamai and huixianhong ), laizhou 953, 8641012, yannong 15 et al were improved wheat cultivars with both excellent agronomic traits and high crossability with rye
