Increasingly, high technology applications in biotechnology and microtechnology industries need to process complex (non-Newtonian) fluids with dispersed particles/droplets in channels as small as several microns (microfluidics). A computational fluid dynamic model of non-Newtonian droplet deformation in microfluidic geometries will be developed, and validated using experimental measurements of the flow field in this project. The aim is to understand and quantify factors influencing droplet deformation. Coupling non-Newtonian characteristics with microfluidic geometries will allow the continuous manufacture of micro-particles of specified size and shape for existing and new applications, and will provide guidance for further extending the process to nano-particle manufacture.Read moreRead less
