Supernova Simulation

Deep inside a dying star in a galaxy far, far away, a carbon fusion flame ignites. Ignition may happen in the middle or displaced slightly to one side, but this simulation explores the consequences of central ignition.  In a localized hot spot, represente

Cross-Channel Flow in a Nuclear Reactor

Interchannel cross-flow is the principal cross-assembly energy transport mechanism for sodium fast reactors. For this design, uniformity temperatures enable peak power output. This Nek5000 simulation modeled the coolant for a 217 pin reactor, using an u

Turbulent Flow of Coolant in an Advanced Recycling Nuclear Reactor

In a thermal hydraulics simulation, we see the turbulent flow of coolant into a mock-up of an advanced recycling nuclear reactor. The colors indicate the speed of the fluid, with red representing regions of high velocity and blue representing regions of l

Hot and Cold Air Entering a Mixing Chamber

From a thermal hydraulics simulation, we see the turbulent flow of air into a mock-up of a mixing chamber of an advanced recycling nuclear reactor. The colors the hot and cold air as they enter the chamber. Two stream surfaces are used to visualize the f

Blood Flow in the Aortic Arch

With new advanced in MRI technology, time-varying blood flow data can be acquired using 4D PC-MRI scanning. This image illustrates right-handed reverse flow of blood in the aortic arch, which has been extremely difficult to visualize in the past. Here,

Vortex Formation on a Delta-Winged Aircraft

As a delta-winged aircraft descends through the atmosphere, the edges of its wings creates vortices, This is a visualization, using stream surfaces with modulated opacity, that shows the formation of a vortex system above a delta wing. The stripes illust

Jet Flow

10,000 streamlines in a jet flow. Sometimes visualization can just produce beautiful images. Christoph Garth, 2010

Rendering of Flow Structures

Illustrative methods mimic those of traditional technical and medical illustrations -- exploiting the perception of the human visual system and providing effective visual abstractions to make the visualizations understandable. This path surface, generate

The Path of a Hurricane

This multi-temporal image depicts summary statistical information gathered from queries of a data set representing hurricane Isabel, the costliest and deadliest hurricane of the 2003 season. The yellow regions indicate the low pressure regions, and one c
