Project description
At DLR there is a research project running in the field of ultrahigh-bypass engines with a counter-rotating integrated shrouded propfan. Its front rotor has 10 blades, rotating clockwise, while the aft rotor has 12 blades rotating anti-clockwise. In the numerical model, the blade count of each rotor has been reduced to 1:1.
The dataset consists of 50 sequences of an instationary time-accurate simulation. We have created a filter to import the dataset into the Visualization ToolKit format, and we have also developed a texture based visualization method which enables to explore the data in a virtual environment in real time. A conical cutting surface is defined, placed into the dataset and the corresponding pressure values are visualized. The radius of the cutting plane and the rotation speed can be controlled interactively by means of a dialog box.
