Abstract

Experiments are conducted to determine the drag of a full-scale cyclist model in a wind tunnel at 4 m/s. The aerodynamic drag is evaluated from tomo-PIV measurements in the wake of the model applying the conservation of momentum within a control volume. The measurements are conducted in a thin volume of 100 x 170 x 3 cubic centimeters using helium-filled soap bubbles as flow tracers. The aerodynamic drag from PIV measurements is compared to standard balance measurements, obtaining an agreement between the two results within 2%.
