STREAMLINE VISUALIZATION OF POTENTIAL FLOW WITH BRANCH CUTS, WITH APPLICATIONS TO GROUNDWATER
ABSTRAKT
The construction of streamlines is one of the most important techniques to visualize flow patterns. Here we describe the method of obtaining streamlines as contour lines of the stream function. We point out advantages in comparison to the more frequently used method of particle tracing. A major plus of the stream function approach is that equidistant spacing of contour levels guarantees that stream tubes between adjacent streamlines conduct the same flow. Thus, illustrations from stream function contouring reveal important flow field information that cannot be obtained so easily otherwise. We address the problem of streamline continuation at branch cuts. A modified contouring is outlined that overcomes the difficulty. We demonstrate the method using applications in the field of groundwater flow with wells.
