Breakthrough in simulation of aircraft wake turbulence
12 March 2008

Researchers made a breakthrough in the simulation of aircraft wake turbulence. Post-docs Philippe Chatelain and Michael Bergdorf, doctoral student Diego Rossinelli, Petros Koumoutsakos, Professor at the Institute of Computational Science of ETH Zurich, and Alessandro Curioni and Wanda Andreoni of the Department of Computational Sciences at the IBM Zurich Research Laboratory in Rüschlikon used high-resolution calculations to simulate, with an accuracy two to three orders of magnitude higher than previously, the vortexes generated when an aircraft takes off or lands. The simulation also visibly revealed how the wake turbulence vortexes become unstable.  (ETHZ)
