WAKE CONVERGENCE DEVICE FOR A VEHICLE

摘要

The present embodiments provide a wake convergence device that allows for the increase in pressure of the low pressure region created behind the “square-shaped” trailing edge of a trailer. The present embodiments also reduce the effect of the trailing edge tip vortices and re-streamlines the flow shedding off the sides and top of the semi-trailer. The wake convergence device mounts to an existing trailer with aerodynamic brackets and hinges in a manner that will not impede a trailer's current practical function for loading and unloading of its payload. The wake convergence device efficiently manages the trailer's trailing edge flow because of its positioning that allows a gap between the wake convergence device and the trailer sides or top.

主权项

1. A wake convergence device for a vehicle having a vehicle top and first and second vehicle sides each extending from the vehicle top, the vehicle including a vehicle leading edge, a vehicle trailing edge, and a vehicle longitudinal axis, the wake convergence device comprising:
a top panel positioned above and spaced from the vehicle top, the top panel including a top panel leading edge that transitions from forward of the vehicle trailing edge to aft of the vehicle trailing edge; a first side panel positioned beside and spaced from the first vehicle side and including a first side panel leading edge that transitions from forward of the vehicle trailing edge to aft of the vehicle trailing edge; and a second side panel positioned beside and spaced from the second vehicle side and including a first side panel leading edge that transitions from forward of the vehicle trailing edge to aft of the vehicle trailing edge.
