Flow around vehicles

The following examples concern flows around different types of vehicles.

Right behind the vehicle, the flow separates and produces complex flow patterns, oscillating in space and time. In many applications, the corresponding drag and lift forces acting on the vehicle are of major interest, and a difficult numerical job to do! The complexity of the problem depends on the:

  • inflow speed
  • viscosity
  • shape of the vehicle
  • size and distance of the vehicle, w.r.t. to the street or the `wind tunnel'

A systematic variation of these different configurations is part of the following flow situations.
