... forming an equilateral triangle. Three-dimensional stereoscopic particle image velocimetry (PIV) was employed to collect the instantaneous velocity data around the arrangements. The study highlights the prime parameters of turbulence such as the mean velocities, Reynolds stresses, turbulent kinetic energy...

...Shicong Li; Xiaoyu Wang; Jing He; Mei Lin; Hanbing Ke An experimental study is carried out to investigate the flow characteristics of the trailing edge of the horizontal vanes mounted at the branch entrance of a T-junction duct by means of particle image velocimetry (PIV). The measured region...

... structure inside the cavity. This approach has not been implemented systematically before and so is explored in the present work. In recent years, nonintrusive and instantaneous measurement methods such as particle image velocimetry (PIV) have allowed detailed quantitative velocity data inside...

... particle image velocimetry (PIV) flow-induced vibration (FIV) turbulent flow short elbow frequency analysis Velocity fluctuation PSD profiles at point E in the shear flow region ( x / D  = 0.3, y / D  = 0.2). ( a ) Velocity fluctuation in the y direction. ( b ) Velocity fluctuation...

... rectangular tank equipped with a side-entering axial flow impeller, scaled down from the industrial agitation of low consistency pulp fiber suspensions, was investigated using particle image velocimetry (PIV) and computational fluid dynamics (CFD), in the laminar regime ( 18 ≤ Re ≤ 120 ) . Tuning of the PIV...
