本文研究了矩形毛细管中对称条件对温度场的影响。通过使用广义通量，即，罗宾类型的边界条件的热传递在这样的毛细管域，它是可能的，以确定明确的条件下，速度场将主要取决于基本参数，因此，什么类型的流动状态可能会出现在毛细管通道。此外，我们还可以得出结论，在什么条件下速度场根本不依赖于其中的一些。这种行为与系统中温度场的对称条件密切相关。在温度分布图中确定了一个“偏斜”或非对称参数W∞;该参数对于研究对称条件对流体力学场的作用以及确定一组限制参数值范围的先验设计标准是有用的。几个数值例子来显示在系统中发现的流动情况。
The role of the symmetrical conditions on the temperature field is studied in a capillary of rectangular geometry. By using the generalized flux, i.e., Robin‐type of boundary conditions for the heat transfer in such a capillary domain, it is possible to identify clearly conditions under which the velocity field will depend crucially on the basic parameters and, therefore, what types of flow regimes may arise in the capillary channel. In addition, it is possible to conclude under what conditions the velocity field will not at all depend on some of these. The behavior is intimately tied to the symmetrical conditions associated with the temperature field in the system. A “skew” or asymmetrical parameter, W∞, has been identified in the temperature profiles; this parameter is useful for studying the role of the symmetrical conditions on the hydrodynamics field and in determining a set of a priori design criteria that limits the range of values of the parameters. Several numerical examples are presented to show the flow situations found in the system.
