Perçin, M. (author), Yazdanpanah, Mahdi (author), Amiri, Human (author), van de Meerendonk, R. (author), van Oudheusden, B.W. (author)This study explores the effects of rotational mechanisms on the characteristics of the leading edge vortex (LEV) by comparing translating and revolving flexible wings that are started from rest. Tomographic particle image velocimetry (tomographic-PIV) technique was employed to acquire three-dimensional flow fields for the revolving wings, while...conference paper 2019

van de Meerendonk, R. (author), Perçin, M. (author), van Oudheusden, B.W. (author)The flow field and fluid-dynamic loads of revolving low-aspect-ratio chordwise-flexible wings are studied experimentally at a Reynolds number of 10,000. The investigation involves phase-locked tomographic particle image velocimetry (PIV) complemented with force measurements. The pressure fields are reconstructed from the three-dimensional...journal article 2018

Schanz, Daniel (author), Huhn, Florian (author), Gesemann, Sebastian (author), Dierksheide, Uwe (author), van de Meerendonk, R. (author), Manovski, P. (author), Schröder, A. (author)We present results from two large-volume volumetric flow experiments. The first of these, investigating a thermal plume at low velocities (up to 0.35 m/s) demonstrates the abilities and requirements to reach volume sizes up to and probably beyond one cubic meter. It is shown that the use of Helium filled soap bubbles (HFSBs) as tracers, combined...conference paper 2016

van de Meerendonk, R. (author), Perçin, M. (author), van Oudheusden, B.W. (author)This study explores the flow field and fluid-dynamic loads generated by revolving low-aspect-ratio flat plate wings undergoing a revolving motion starting from rest. Three wings with different degree of chordwise flexural stiffness (i.e., rigid, moderate flexibility and high flexibility) have been tested in order to investigate the influence of...conference paper 2016

van de Meerendonk, R. (author), Perçin, M. (author), van Oudheusden, B.W. (author)This study explores the flow field and fluid-dynamic loads generated by revolving low-aspect-ratio wings. The pressure field and load characteristics are successfully reconstructed from the phase-locked tomographic measurements in three independently measured volumes along the span of the wing. The vortical structures encompass a low pressure...conference paper 2016
