This paper describes a high-speed video acquisition system designed for visualization in fluid mechanics. The need for a non conventional video system is shown. The architecture of a typical experiment of flow visualization is discussed along with the whole video acquisition system. The camera, built around the EEV CCD37 sensor, with a resolution of and a rate of 100 non-interlaced images per second, is then described in detail. Finally, examples of images obtained with our system are given to illustrate the most typical situations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
