As part of Visweek 2011, the IEEE has announced details its annual Visualization Contest.
This year the contest focuses on computational fluid dynamics:
The goal is to devise a visualization that allows for exploring the stability of a fluid dynamics simulation of a pump with respect to different models of its turbulences. One big challenge is the large amount of the data. The contest aims at demonstrating how novel visualization and interaction techniques from the fore-front of scientific research can help to solve real-world problems of high relevance - today.
Prizes include an iPad, free registration at VisWeek 2011 and certificates for team members. The competition deadline is July 31, 2011.
Data sets and more details are available from the contest web-site.
