Small Grants for Exploratory Research: A New Graphical Method for Numerical Modeling in Flow Domains with Complex and Deforming Boundaries

这是一个SGER项目。提出了一种二维和三维单相流和多相流的图形化编程方法。流量域是使用空间向量绘制的，空间向量为任何复杂的流动情况提供输入数据。通过使用一组有限的图形功能，可以用单色或多色将信息直接可视化在计算机屏幕上。这种方法大大减少了编程时间，使用了更少的计算机内存，并允许以更高的局部化分辨率进行建模，方便快捷地交互访问数据。该方法特别适用于多区域流动问题，如多相流。该方法简单，利用现有硬件，在多维复杂流动中有较好的性能。该方法适用于工作站环境。

This is an SGER project. A graphical programming method is proposed for single and multiphase flows in two and three- dimensions. The flow domain is drawn using spatial vectors, which provide the input data for any complex flow situation. The information may be directly visualized on a computer screen by using a limited set of graphics functions, with single or multiple colors. The method reduces significantly the programming time, uses much less computer memory, and allows for modeling with increased localized resolution, easy and fast interactive access to data. The method particularly useful for multidomain flow problems, such as multiphase flows. The method is simple, make use of the existing hardware,a nd may lead to good performances in multidimensional complex flows. The proposed approach is suitable for the workstation environment.
