Project Description
Semi-Trailer
Researching Drag Reduction
DARcorporation engineers modeled and simulated a semi-trailer for the purpose of researching drag reduction devices for such vehicles. The simulation in the first photo shows static pressure on the aft end of the semi-trailer. The results of which are used as the baseline for testing drag reduction devices. The simulation in the second photo shows velocity contours over the semi-trailer which highlights the large wake that exists behind all semi-trailers. DARcorporation is researching various devices that will reduce the drag caused by these wakes by over 15%, which helps reduce fuel costs and emissions.

This image shows the static pressure on the aft end of a semi-trailer traveling at 55 mph. The results of this simulation are used as the baseline for testing drag reduction devices for similar semi-trailer vehicles.
