Study on curl-based streamribbon visualization

  • Streamribbon visualization,one of the important techniques for CFD(computational fluid dynamics) vector fields visualization,was investigated. On the basis of the analysis on existing algorithms regarding streamribbon generation, the stress was laid on the streamribbon generation algorithm based on the curl in vector fields. The implementation of this algorithm is explained in detail. In order to solve one of the key points in the algorithm, principles of differential calculus on compound functions was introduced to calculate the curl in data sets of three-dimensional steady vector fields with irregular structured grids. The streamribbon generation algorithm based on curl is of lower complexity, as well as is of higher robusticity and tractability. The resulting visualization images of streamribbon conduce to the study on the vortices in flow fields.
