Computational Fluid Dynamics (CFD) methods have opened a new field to
perform aerodynamic studies saving money and time. The difficulties presented by this
method to calculate complex flow field problems imply that CFD validation is needed to
provide correct results. Experimental data have recently been used to validate the accuracy of CFD
predictions. Particle Image Velocimetry (PIV) has shown to be a powerful tool in the investigation
of complex flows. The aim of this paper is to present results from PIV experiments
that would be interesting for CFD validation.
Regarding aircraft operations, the short runway available implies the necessity of equipment which
helps to take-off performances. Ski-jump ramp system improves aircraft performances by an
increment of lift resulting in successful take-off operations. The ski-jump ramp presence
generates a complex flow bounded by a turbulent shear layer and a low velocity
recirculation bubble over the end of the flight deck. The adverse effects on the
aircraft aerodynamics affect to pilot safe operations, so this region is an interesting
problem to be
studied by means of wind tunnel experimental tests
