Supercomputer Models Frozen Water Droplets

[index] [473 page views]

The Department of Energy offers a portion of its massive, 20+ petaflop supercomputer Titan up to the public for scientific research. Recently, GE engineers updated an older code base for simulating how a water droplet freezes to make use of Titan's mammoth array of NVidia GPUs to nearly quintuple the simulation's performance. Of course the purpose wasn't to merely run the simulation faster, it was to run a deeper simulation increasing the model to one million water molecules in order to study how the droplet freezes. As a result of the research, scientists can develop better anti-icing materials for things like wind turbines in the arctic or off-shore drilling rigs. A time lapse video of the droplet's freezing can be viewed here: https://www.olcf.ornl.gov/2013/10/25/titan-propels-ge-wind-turbine-research-into-new-territory/
