Micro-Particle Image Velocimetry (µPIV): Recent developments, applications, and guidelines

Abstract

In this review we discuss the state of the art of the optical whole-field velocity measurement technique micro-scale Particle Image Velocimetry (microPIV). microPIV is a useful tool for fundamental research of microfluidics as well as for the detailed characterization and optimization of microfluidic applications in life science, lab-on-a-chip, biomedical research, micro chemical engineering, analytical chemistry and other related fields of research. An in depth description of the microPIV method is presented and compared to other flow visualization and measurement methods. An overview of the most relevant applications is given on the topics of near-wall flow, electrokinetic flow, biological flow, mixing, two-phase flow, turbulence transition and complex fluid dynamic problems. Current trends and applications are critically reviewed. Guidelines for the implementation and application are also discussed.

“…We applied non-invasive micro-particle image velocimetry (mPIV), reviewed in detail elsewhere, 26 to characterize the fluid flow in spots A and B (cf. Fig.…”

Particle imaging techniques for volumetric three-component (3D3C) velocity measurements in microfluidics

“…A more general overview of visualization techniques for micron scale flows is presented by Sinton (2004). Reviews of the state of the art of lPIV and its relevant applications were published by Lindken et al (2009) and Wereley and Meinhart (2010). Guidelines for a proper experimental design in particular are given by Lindken et al (2009) and Raffel et al (2007).…”

However, the inherent limitations of standard lPIV, using just one camera are -The technique relies on volume illumination; thus the minimal thickness of the measurement plane is determined by the imaging optics' depth of focus.…”

Fabrication, Operation and Flow Visualization in Surface-acoustic-wave-driven Acoustic-counterflow Microfluidics

“…Depending on the size of the beads and the visualization technique, the optics required may change. Particle concentration depends also on the experimental purpose: in the case of mPIV low particle concentration is preferred 14,24 , but large particle concentration allows for better statistic and qualitatively visualized streamlines in single images. The particle solution should be monodisperse and without clusters for both qualitative and quantitative understanding of the particle velocity fields.…”
