PIV-based Non-intrusive Determination of Unsteady Aerodynamic Loads (07645)

Project nummer: 07645

Omschrijving van het onderzoek

The research aims at the development and application of a novel non-intrusive experimental method to determine the aerodynamic loads on objects from flow velocity data. The load determination is achieved by combining the flow field information with basic integral momentum principles according to Newton's third law (action = - reaction). The flow velocity is measured by a technique called Particle Image Velocimetry (PIV), which relies on following the motion of particles transported by the flow.
The PIV-based loads-determination technique has been validated for flows that are constant in time, or for time-average values of the loads. However, the recent developments of the PIV technique, including high speed illumination-imaging systems, provide nowadays the perspective to perform time-resolved flow measurement. This would enable the determination of instantaneous loads in unsteady flows.
More in particular, the present project will address the development of procedures, in terms of hardware solutions, experimental arrangements and data post-processing, in order to make it a technique that can be applied relatively routinely in fluid-dynamic research practice. The primary area of application is that of low-speed aerodynamics and industrial fluid dynamics, wind engineering in particular. The extension of the method to the high-speed flow regime will also receive attention, in view of its relevance for industrial aeronautical practice.
