This note shows that for a BVP of Poisson's equation withQm(u, v) as its source function, a direct evaluation of some integrals yields the same exact results as obtained by similarity analysis.


Based on a similarity analysis and the experimental data, an empirical scaling formula was proposed so that the tangential component of the turbulence kinetic energy was dependent only on the parameter of the contraction ratio.


By similarity analysis, we also show that the debinding rate and flow field are similar at various temperatures for the same compactwick combination.


A similarity analysis was performed using regional records of Copepoda and including two taxa, the orders Calanoida and Cyclopoida.

 In this paper the physical and mathematical models for the plane atomized jet are suggested considering the variation of flow quantities in different regions. By some simplification and similarity analysis the half thickness of the plane atomized jet, the half thickness of air entrainment region, the half thickness of the jet core region and the concentration at the interface of air enchainment region and mixing region were calculated numerically, and the results was also compered with experimental results....

It was found that the two results are in close agreement with each other.  本文根据部分掺气散裂射流的特性，提出了相应的物理模式与数学模式，并通过简化与相似分析得到了掺气散裂射流的半宽，水挟气泡区的半宽，水核区的半宽和时流掺混区与水挟气泡区边界处的含气浓度随射流初始条件的变化。并将计算结果与实验结果进行了比较，结果表明，两者甚为一致。  The Francis turbine runner is an important running part of under water. Because of the stimulation of the unstable field of the water, the blade would be fatigue failure by the unstable hydraulic stress. To analyze the reason, the dynamic analysis of the turbine runner is needed. According to the analogy analysis of vibration of the object in the air and under the water and the mode analysis of the runner in the air, the dynamic characteristics of the runner under the water will be analyzed.  混流式水轮机转轮是重要的水下旋转部件。由于水力不稳定流场的激励作用，使叶片产生动应力而容易引起疲劳破坏。在分析其原因时，转轮动态特性的研究是必不可少的。本文通过振动相似分析物体在空气中和液体中的相似关系，以及转轮在空气中的模态分析，进而分析转轮在水中的动态特性。  This study presents the method to determine sediment concentration scale in movablebed model experiments.Firstly various methods by other researchers are reviewed,and it is concluded that the scale deduced by the equation λs and could not meet the similarity condition for the riverbed deformation.The reasons causing errors are as follows:(1) the semiempirical formula for sediment transportation capacity was adopted in the process of similarity analysis,which could not be synchronously applied on the model... This study presents the method to determine sediment concentration scale in movablebed model experiments.Firstly various methods by other researchers are reviewed,and it is concluded that the scale deduced by the equation λs and could not meet the similarity condition for the riverbed deformation.The reasons causing errors are as follows:(1) the semiempirical formula for sediment transportation capacity was adopted in the process of similarity analysis,which could not be synchronously applied on the model and the prototype;(2) The coefficient scale was assumed to be 1;(3) The effect by the turbulence and diffusion of λω had not been taken into account in the similarity criteria of movablebed model with suspended load.Then a feasible approach is recommended to calculate the sediment concentration scale by the sediment transportation capacity of the model and the prototype.At last,three series of experiments were implemented to search the relationship of the sediment concentration scale between the riverbed deformation similarity,and the result illustrated that the riverbed evolvement in the model experiment was more similar to that in prototype while the sediment concentration scale is close to dry density scale.  本文在评述目前关于含沙量比尺确定方法的基础上,指出前人采用sλ确定的含沙量比尺,不能满足水流挟沙相似条件。剖析所找的原因是相似分析时,采用了不能同时适用于原型和模型且简化成指数等于1的半经验水流挟沙力公式,推导过程中又引入系数比尺等于1的假定,并以不考虑紊动扩散作用影响的λω作为泥沙悬移相似条件。选用容重适中的模型沙所开展的试验论证结果表明,含沙量比尺的大小对河床变形相似有直接影响,该比尺小于1时河床变形与原型偏差较大,该比尺与淤积物干容重比尺相近时,模型同原型才较为相似。此外,文中还认为,目前确定含沙量比尺的办法最好是通过分别确定原型和模型水流挟沙力的途径来实现。
