The World Solar Challenge is a solar-powered car race, which cover 3021 km from Darwin to Adelaide. Most of the vehicles participating at this race can be defined as Ultra-Streamlined body; the drag being mainly produced by skin friction. In designing such vehicle, it is important to localize the area where transition from laminar to turbulent flow will occur. The location of transition will affect the overall drag coefficient of the vehicle. Moreover its determination by CFD simulation is a

The infrared thermography is applied on a scaled model of the Umicore solar car, which was designed for the World Solar Challenge.
