求解过程中，由于几何模型发生变化而导致区域网格改变时会出现几何结构的连续性问题。本章中，我们举两个例子——流道中由于不同尺寸孔板引起额外压力损失问题是稳态几何连续性的一个例子。从概念来看，这个问题与第5章贝纳尔问题中通过Rayleigh数进行的变量连续性没什么不同。第二个例子是液体中悬浮的乳胶颗粒的干膜。在这个问题中，考虑了两个移动前缘；一个通过坐标变换，另一个通过光滑界面模型。该技术对于之前模拟该问题采用的移动弱项方法有所改进。(Solving process, due to geometry changes and the continuity of the geometric structure of the regional grid changes. In this chapter, we give two examples- the flow channel due to the different size orifice caused by the additional pressure loss is an example of the steady-state geometric continuity. Variable continuity standpoint, this issue in Chapter 5 Bernal Rayleigh number is no different. The second example is a dry film of the latex particles suspended in the liquid. In this problem, consider the two move the leading edge a coordinate transformation, and the other by the smooth interface model. The technology used before to simulate the mobile weaknesses improvements.)
