Characteristics of Hydrodynamically Focused Streams for Use in Microscale Particle Image Velocimetry (Micro-PIV)

Abstract: This paper presents the characteristics of hydrodynamically focused streams to be used in Microscale Particle Image Velocimetry (micro-PIV). The investigation was done by means of Confocal Laser Scanning Microscopy (CLSM) in channels of cross sections 260 × 200 μm and 1040 × 800 μm, within the downstream velocities range from 0,1 to 2,5 cm/s. The formulation of a curvature of the sheet, its dependence on the side stream ratio and overall downstream velocity is discussed qualitatively and quantitatively. The re… Show more

“…FCS was employed to probe fluids behavior after their manipulation in microchannels especially for mixing and sorting (Yeh et al 2006;Dittrich and Schwille 2003). Recently, other methods were employed for the characterization of hydrodynamic focusing, such as the micro-PIV (Domagalski et al 2007) and the voltammetric analysis (Deshpande et al 2009). Micro-PIV is a wide spread and powerful technique for the characterization of flow velocity in microfluidic devices especially at very low flow rates of the order of 500 lm s -1 , as demonstrated by many reviews in the field (Sinton 2004;Wereley and Meinhart 2010).…”

“…All these numerical models and simulations consider perfectly symmetric flux conditions between the two lateral channels and focus their attention mainly on the width of the central flow (Wang et al 2008). Lee et al (2006) showed an asymmetric hydrodynamic focusing device in a two-dimensional model applied to polystyrene microparticles, while Domagalski et al (2007) reproduced the asymmetric flux in a simple cross (squared section) centering their attention on the sheet curvature along the plane normal to the flux direction.…”

“…As it has been stated earlier, when the flow is focused by identical side streams Q A =Q B , the focused stream leaves a microchannel flowing in the center of the outlet channel. In the case when the focusing streams are not symmetric, the focused stream is pushed away from the channel axis Domagalski, 2008;Domagalski, 2011).…”

“…Recently, the flow focusing method was proposed to introduce the tracers as a thin layer instead of whole volume seeding (SeS-PIV Selective Seeding PIV) Domagalski et al, 2008;Blonski et al, 2011;Domagalski, 2011). Such layer can be obtained in a rectangular cross-section channel via hydrodynamic focusing, which is shown in Fig.…”
