Abstract
The aerodynamic wind tunnel at Volvo Cars, known as the PVT, was recently upgraded to a moving ground wind tunnel to improve simulation quality. The moving ground simulation system consists of a 5-belt rolling road system (a centre belt and four wheel drive units). Flow simulation has also been improved by a new boundary layer control (BLC) system with a basic suction scoop, large distributed suction areas and aft belt tangential blowing. In addition, the wind tunnel main fan motor has been up-graded from 2.3 MW to 5 MW to provide a wind speed of 250 km/h in the full test section. Previously, 250 km/h was achieved only by installing inserts to reduce the test section area.
The present paper provides an outline of the design features, philosophy of the new systems, aerodynamic calibration and commissioning results.
