Book Description
This thesis is a compiled collection of works on the development of Particle Image Velocimetry (PIV) and micro PIV for near-wall flow measurements. PIV has been used to study many large scale industrial and biological flows, and micro PIV is increasingly utilised in micro-biological and micro-fluidic flow measurements. Both of the methods however suffer significant errors in the measurements of near wall flows due to the effects of the wall boundary and high velocity gradients. In addition, micro PIV suffers significant errors due to volume illumination and the resultant imaging of out-of-focus particles. Many important phenomena such as near-wall turbulence, near-wall transportation of particles or blood cells occur in near-wall regions, and significant improvement of PIV and micro PIV is required. This thesis is devoted to providing solutions to this demand by proposing three new PIV and micro PIV measurement techniques: image overlapping, volumetric-correlation PIV and interfacial PIV. Although these techniques can be applied to general applications, they have been optimised for biological applications. Image overlapping, when applied to micro PIV data, improves the measurement accuracy by effectively reducing the effect of out-of-focus particles. In micro PIV the imaging of out-of-focus particles by volume illumination causes significant measurement bias over the measurement depth. Image overlapping improves measurement accuracy significantly more than currently available techniques, while requiring fewer computational resources. In contrast to improving micro PIV accuracy by reducing the out-of-focus effect, volumetric-correlation PIV (VPIV) utilises this effect to provide 3-dimensional, 2-component (3D2C) velocity fields. VPIV is further extended to uniquely measure particle concentration. The concentration measurements improve the velocity measurement accuracy and provide additional information to study near-wall particle transport phenomena. VPIV simplifies 3D velocity measurements while requiring cheaper hardware. Challenging PIV and micro PIV measurements of flows near curved walls are further resolved by interfacial PIV. In this technique the fluid regions near curved walls are straightened by conformal transformation and a wall-normal velocity profile, with one-pixel resolution, is obtained utilising a novel line-correlation function and curve fitting.Interfacial PIV substantially simplifies the manual image rotation normally required in traditional PIV techniques, while increasing both the resolution of the near-wall velocity profiles and the accuracy of the wall-shear velocity gradient.

Book Description
Microfluidics is a young and rapidly expanding scientific discipline, which deals with fluids and solutions in miniaturized systems, the so-called lab-on-a-chip systems. It has applications in chemical engineering, pharmaceutics, biotechnology and medicine. As the lab-on-a-chip systems grow in complexity, a proper theoretical understanding becomes increasingly important. The basic idea of the book is to provide a self-contained formulation of the theoretical framework of microfluidics, and at the same time give physical motivation and examples from lab-on-a-chip technology. After three chapters introducing microfluidics, the governing equations for mass, momentum and energy, and some basic flow solutions, the following 14 chapters treat hydraulic resistance/compliance, diffusion/dispersion, time-dependent flow, capillarity, electro- and magneto-hydrodynamics, thermal transport, two-phase flow, complex flow patterns and acousto-fluidics, as well as the new fields of opto- and nano-fluidics. Throughout the book simple models with analytical solutions are presented to provide the student with a thorough physical understanding of order of magnitudes and various selected microfluidic phenomena and devices. The book grew out of a set of well-tested lecture notes. It is with its many pedagogical exercises designed as a textbook for an advanced undergraduate or first-year graduate course. It is also well suited for self-study.

Book Description
The development of micro- and nanodevices for blood analysis is an interdisciplinary subject that demands the integration of several research fields, such as biotechnology, medicine, chemistry, informatics, optics, electronics, mechanics, and micro/nanotechnologies. Over the last few decades, there has been a notably fast development in the miniaturization of mechanical microdevices, later known as microelectromechanical systems (MEMS), which combine electrical and mechanical components at a microscale level. The integration of microflow and optical components in MEMS microdevices, as well as the development of micropumps and microvalves, have promoted the interest of several research fields dealing with fluid flow and transport phenomena happening in microscale devices. Microfluidic systems have many advantages over their macroscale counterparts, offering the ability to work with small sample volumes, providing good manipulation and control of samples, decreasing reaction times, and allowing parallel operations in one single step. As a consequence, microdevices offer great potential for the development of portable and point-of-care diagnostic devices, particularly for blood analysis. Moreover, the recent progress in nanotechnology has contributed to its increasing popularity, and has expanded the areas of application of microfluidic devices, including in the manipulation and analysis of flows on the scale of DNA, proteins, and nanoparticles (nanoflows). In this Special Issue, we invited contributions (original research papers, review articles, and brief communications) that focus on the latest advances and challenges in micro- and nanodevices for diagnostics and blood analysis, micro- and nanofluidics, technologies for flow visualization, MEMS, biochips, and lab-on-a-chip devices and their application to research and industry. We hope to provide an opportunity to the engineering and biomedical community to exchange knowledge and information and to bring together researchers who are interested in the general field of MEMS and micro/nanofluidics and, especially, in its applications to biomedical areas.
