flows to other surfaces and cooling systems. Rubber tyre debris from the soft compounds used in such series can become attached to the wing,
reducing downforce, increasing drag and altering the wake characteristics of the wing. This work studies, through force balance and Particle Image
Velocimetry (PIV) measurements, the effect a piece of debris has on an inverted double element wing in ground effect. The debris is modelled using
a hard-setting putty and is located at different span and chord-wise positions around the wing. The sensitivity to location is studied and the effect on
the wake analysed using PIV measurements. The largest effect on downforce was observed when the debris was located on the underside of the wing
towards the endplates. The wake was most effected when the debris was located closest to the gap, generating a large fluctuating wake with a
significantly different path to the baseline case.
