Understanding Tractor Trailer Aerodynamics Using a Time Accurate Approach

Application Pointwise has released the webinar, Understanding Tractor Trailer Aerodynamics Using a Time Accurate Approach, which shows how multi-block hybrid meshing techniques can improve mesh quality and concentrate mesh density in areas of interest.

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.

Watch this webinar showing how SU2 was used for a transient simulation conducted to capture near body drag and wake drag phenomena 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.

Discover how to:

  • Manage mesh topology to improve mesh 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 using Pointwise.

Watch the webinar:

Aeromutable is bringing aerospace technology into the trucking industry. We are focused on the design and manufacture of aerodynamic modification systems that increase vehicle efficiency and safety. Our first product is a non-intrusive trailer add-on system that, through dynamic air injection, improves aerodynamic performance and reduces fuel consumption and carbon emissions—allowing the trucking industry to increase profitability while reducing its carbon footprint.

Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today – reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured, overset and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT® and CFX®, STAR-CCM+®, OpenFOAM®, and SU2 as well as many neutral formats, such as CGNS; runs on Windows, Linux, and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Manufacturing firms and research organizations worldwide have relied on Pointwise as their complete CFD preprocessing solution since 1994.
