However, many contemporary and former research on this topic has confirmed the drag reducing effect but very less is known regarding how blowing is effecting the Reynolds stresses at high Reynolds number. Therefore, effect of uniform blowing has been experimentally investigated using Stereo Particle Image Velocimetry (SPIV) measurements in a zero pressure gradient turbulent boundary layer (TBL). The data presented in this literature covers a large range of high Reynolds number flow e.g. Reθ = 7500∼19763 where Reynolds number is based on the momentum thickness. Upstream blowing was varied from 1\%∼6\% of free stream velocity and measurements were taken downstream after a short interval. Logarithmic and outer region of the TBL was given special attention in terms of investigating statistics and turbulence properties.}, language = {en} } @misc{SzaboMeierMeyeretal., author = {Szabo, Peter and Meier, Martin and Meyer, Antoine and Barry, Elhadj and Motuz, Vasyl and Mutabazi, Innocent and Egbers, Christoph}, title = {PIV and shadowgraph measurements of thermo-electrohydrodynamic convection in a horizontal aligned differentially heated annulus at different gravity conditions}, series = {Experimental Thermal and Fluid Science}, volume = {129}, journal = {Experimental Thermal and Fluid Science}, issn = {1879-2286}, doi = {10.1016/j.expthermflusci.2021.110470}, language = {en} } @incollection{MeierSzaboMotuzetal., author = {Meier, Martin and Szabo, Peter and Motuz, Vasyl and Egbers, Christoph}, title = {Str{\"o}mungsfeldvisualisierung von thermo-elektrodynamischer Konvektion mit einer kombinierten PIV- und Schattentechnik}, series = {Experimentelle Str{\"o}mungsmechanik : 28.

The experiments were conducted during parabolic flight campaigns. In the present study, our primary focus was on the saturation of perturbations induced by thermo-electrohydrodynamic instability. The effect of initial flow conditions on perturbation growth rates is examined when entering the microgravity phase. Furthermore, a series of experimental setups with varied lengths and aspect ratios were considered to investigate the impact of geometry on flow behavior. The present study quantitatively investigated the flow using particle image velocimetry in the meridional and radial-azimuthal planes. Furthermore, direct measurements were taken of the global response of the flow, in this case heat transfer, using a heat flux sensor attached to the outer cylinder wall.}, language = {en} }
