Expérimental et théorique
The aim of the internship is to demonstrate the feasibility of a method employing fluorescent rotors to measure local shear-stress and/or viscosity in micro-scale flows. Once validated, the method will be used for shear-stress measurement in an acoustofluidic device (with potential application in cell manipulation). The project will involve the following tasks Literature review on previous studies on fluorescent rotors and dyes employed Fabrication of fluid samples, micro-channels Benchmark experiments on a straight micro-channel flow Experiments on a straight micro-channel flow with complex fluids Experiments in an acoustofluidic device with simple fluids Data processing and presentation
