Abstract:

We have simulated the mixing in a shear layer due to the Kelvin-Helmholtz instability using molecular dynamics. In order to reach micron-sized simulations, we have simulated a total of 9 billion atoms on a 212,000 CPU supercomputer. We have analyzed the growth of the mixing layer and compared the results to conventional Navier-Stokes simulation of the mixing process.
