Abstract
When a lot of data are processed in a computer, flow visualization by such a figure process as drawing streamlines and equivorticity lines is very important to find new phenomena from the data. Here, some flow patterns are visualized on a X-Y plotter or a graphic display. In this method, streamlines or equivorticity lines are able to be plotted using stream function or vorticity at a constant interval for two-dimensional orthogonal curvilinear coordinates system. In this paper, an initial flow around a uniformly accelerated elliptic cylinder in an incompressible flue is analyzed from at rest by a finite-differnece method and time histories streamline and lines of constant vortcity are shown.
