Rethinking a Century of Fluid Flows

In 1922, English meteorologist Lewis Fry Richardson published Weather Prediction by Numerical Analysis. This influential work included a few pages devoted to a phenomenological model that described the way that multiple fluids (gases and liquids) flow through a porous-medium system and how the model could be used in weather prediction.…

OLCF Postdoc Fuses the Gap Between Experiment and Computation

Ada Sedova, a postdoctoral research associate at the Oak Ridge Leadership Computing Facility (OLCF), develops computational calculations for supercomputing codes. In front of the OLCF’s Titan supercomputer, Sedova displays a spectrum from her experimental work, measuring the vibrational frequency of nucleobases (bases of DNA and RNA) at the Spallation Neutron…

A Helping Hand

For many researchers, Titan is only part of the picture; managing and understanding data are quickly becoming as important as the simulations that create it.

Investigating the Earth’s Inner Workings

Princeton's Jeroen Tromp is part of a team using Oak Ridge National Laboratory’s (ORNL’s) Titan supercomputer, to reveal the Earth’s inner workings via adjoint tomography simulations, or monitoring the interaction of a forward wavefield, in which the waves travel from the source to the receivers, and an “adjoint” wavefield in…
