  1. Numerical stability, the other issue of the lattice boltzmann method, is discussed in chapter 5. corresponding to the uniform and shear background flow, the stability of d2q7 d2q9 and d3ql5 model is analyzed through the von neumann linear stability theory, both the conclusion about the mass distribution parameters, the wave number, the relaxation time and the uniform velocity, and the linear stability criterion n r0. 58 are instructive to numerical simulation of flow

    第五章考慮了數值方法另外一個方面的問題，在均勻流和剪切流兩種背景流場下，運用vonneumann線性分析法，針對d2q7 、 d2q9及d3q15格子模型，分析了質量分佈參數、波數、鬆弛時間和平均流速等決定模型穩定性的主要參數對模型穩定性的影響，得到了對流場數值計算具有指導意義的一般性結論與線性穩定性標準n r _ e ~ （ 0 . 58 ） 。
  2. Based on the analysis of characteristics of sediment particle concentration distribution, it is pointed out that the diffusion theory can describe sediment concentration distribution in main flow region but cannot explain sediment concentration distribution law near bottom because of the existence of sediment colliding shear stress

    摘要在分析泥沙顆粒含量分佈特性的基礎上，指出擴散理論能較好地描述主流區的泥沙含量分佈規律，但在近底流區由於泥沙碰撞切應力的存在，使得擴散理論不能解釋此區域的泥沙含量分佈規律。
  3. Abstract : this paper analyzes the essential features of bend flow, describes the relationship between submerged vanes characteristics and induced bed shear stresses, give the theory and design procedure of bank protection of river bend by using submerged wanes

    文摘:本文分析了彎道水流的基本特性，闡述了充分淹沒在水下的導流屏特性和由此引起的河床剪應力之間的關系，給出了彎段河道導流屏護岸原理及設計方法。
