Understanding Unsteady Aerodynamics of a Tractor-Trailer Configuration

In this prerecorded webinar, you will see SU2 used for a transient simulation conducted to capture near body drag and wake drag phenomena for a tractor-trailer configuration with a Delayed Detached Eddy model based on the Shear Stress Transport turbulence. The control over mesh topology and boundary layer generation within Pointwise provided a mesh best suited for this simulation.

In the United States, 70 percent of freight tonnage is transported by tractor trailers each year. Tractor trailers spend much of their time at highway speeds, resulting in 65 percent of their fuel consumption being used to overcome aerodynamic drag. Consequently, it is essential to understand the source of this aerodynamic drag and computational fluid dynamics (CFD) is the perfect tool to identify and diagnose these issues.

Topics covered during the webinar include

  • Manage mesh topology to improve quality and intelligently resolve flow phenomena.
  • Gain insight into the systemic aerodynamic drag problem faced by the commercial trucking industry.
  • Mitigate geometric pinch points in the tire-ground contact regions.

Your hosts for this webinar are Dr. David Manosalvas-Kjono, the co-founder and CEO of Aeromutable, and Pointwise’s Josh Dawson.

Don’t delay – watch today. Find out how flexible preprocessing that conforms to you needs and not the other way around is key to insightful CFD.
