Proceedings of the Institution of Mechanical Engineers, Part G: journal of aerospace engineering, Volume 220, Issue 6, May 2006, pp. 619-6270954-4100http://dx.doi.org/10.1243/09544100JAERO75http://dspace.lib.cranfield.ac.uk/handle/1826/7506This article presents two over-looked post-processing techniques which provide the investigator with additional tools for data analysis and visualization. Both techniques exploit the trend for planar experimental data collection and are implemented in two-dimensions. Critically, both techniques are suitable for use on computational and experimental datasets, require no a-priori knowledge of the flow-field, and minimal user interaction during processing. Firstly, line integral convolution will be introduced as an alternative to streamline or in- plane velocity vector visualization. Secondly, a feature identification procedure will be outlined that can be used to reduce datasets for clearer visualization and provide quantitative information about topological flow features.Article
