In a context of reducing greenhouse gas emissions, it is necessary to act on all the levers to reduce the consumption of heavy goods vehicles. At a speed of around 85 km/h, more than 40% of the vehicle’s power is used to counteract the effect of the air.

Elaborate a CFD model to test different solutions to reduce the drag force and therefore the consumption of trucks.

The drag force is 75% due to the trailer, 50% of which is at the underframe and rear of the trailer. SEGULA has designed aerodynamic artifacts in the underframe to direct the air flow onto the wall and thus reduce the wake at the rear of the vehicle.
