Description
This poster will present how the use of the SNIC computational resources has been
used by the authors to explore the flow physics of a simplified tractor-trailer
model. Even though the geometry is rather simple, the flow around a simplified
tractor-trailer model is very complex. It is characterized by large, unsteady
vortices that are shed from the geometry. The interaction of these vortices with each
other and the geometry will determine important aerodynamic properties such as the
drag and lift of the vehicle. The SNIC resources has enabled us to use the
computational costly but more accurate unsteady Large Eddy Simulation (LES) approach
when solving the governing Navier-Stokes equation. This enables us to better analyze
and understand the unsteady nature of the flow. The poster will
show varius results from our research.
