Greater understanding the phenomenon of flight has resulted in significant advances in aviation. The Wright Brothers defined the control of an aircraft in three dimensions (pitch, roll and yawl) and thus advanced the science of aviation. Today’s studies are examining with a super computer turbulent flow variables’ velocity, temperature and pressure to make engines more green.

Powerplants propel and create noise. One approach to reducing the noise results in lower engine efficiency. Researchers at GE Engines, GE Global Research and Argonne National Laboratory are examining the above↑ picture of a flow structure with Argonne’s Leadership Computer Facility. The below↓article describes the potential of such research.

Specifically, “[r]esolving the wall bounded turbulent flow around a wind turbine” requires the Argonne’s 10-petaflops Mira supercomputer (in case you do not know what a petaflop is, here’s a link) to assess key flow physics of this multi-scale turbulent mixing phenomenon and thus how the interior of a turbine might be designed to reduce the noise while reducing fuel consumption.

It is amazing how the power of computers can create patterns from seemingly random phenomenon and create solutions. This joint effort may simultaneously advance aerodynamics and the environment.

MOST PROMISING!!!
