- The solution algorithm involves tracing the characteristic lines backwards in time from a upwind element of an interior point . two advanced mehtods , quasi - consistence and consistence hexahedral element method , for three - dimensional advective problem are developed . and comparison of these two methods with linear interpolating function method is implemented
当re 400时，流动明显地具有二维性； re 800时，流动具有一定程度的三维性，而且出现了次回流区； re 1000时，流动则具有明显的三维性。 - Important missing aspects are : turbulent flow , numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution , variable property fluids , boundary layers , stability , etc . rather , it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ) . numerical problems associated with advective dominated transport include spurious oscillation , numerical dispersion , peak clipping , and grid oriention . however , the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function , which can keep the computational stability and low damping
3 、针对三维纯对流方程提出了实用的拟协调单元模式，并与线性插值模式和协调单元模式比较后表明，在物理量大梯度变化的情况下，线性插值模式会产生较大的数值阻尼，导致解的失真；协调单元模式具有极高的计算精度和良好的计算稳定性，还可较好地克服数值阻尼，但由于计及物理量的二阶导数项，计算工作量大，边界条件给定尚存在一定的困难；而拟协调单元模式不仅具有协调单元模式计算精度高的优点，还避免了物理量的二阶导数项，可大大地减少计算工作量。 - Secondly , a new adaptive osculatory rational interpolation kernel function is constructed from the point of approximating the ideal interpolating function , the function ' s characteristics , i . e . , the space properties , the spectral properties , and the efficiency are analyzed , and the comparision it with other interpolation methods is made
然后，在图像采样和图像重建理论的基础上，基于逼近理想插值核函数的思想，构造了一种自适应切触有理插值函数，对其空域和频域的性能进行了分析，并与传统的图像插值核函数进行了比较。
