Abstract

Streamline construction is one of the most fundamental techniques for visualizing steady flow fields. Streamribbons and strsamtubes are extensions for visualizing the rotation and the expansion of the flow. This paper presents efficient algorithms for constructing streamlines, Streamribbons, and streamtubes on unstructured grids, A specialized Runge-Kutta method is developed to speed up the tracing of streamlines. Explicit solutions are derived for calculating the angular rotation rates of Streamribbons and the radii of streamtubes. In order to simplify mathematical formulations and reduce computational costs, all calculations are carried out in the canonical coordinata system instead of the physical coordinate system. The resulting speed-up in overall performance helps explore large flow fields.
