Jeudi 30 janvier à 11h00 ; salles des séminaires IRPHE
In this seminar, I will talk about different aspects of microfluidics, going from evaporation with transport of particles to acoustic streaming. The similar experimental approach for these phenomena, is based on microfluidic set up, where the channel, of sizes spanning from 200µm to 1mm, is set on a microscope and filled with fluorescent 1µm diameter particles to follow the fluid flow. During my PhD, we tackled the physics of evaporation from a pore size channel, how particles and contact angles influence it, to a model porous medium under different environmental conditions. From my post-doctoral research, I will discuss how focused ultrasounds induce acoustic streaming in microchannels, the µPIV treatment and how I have used Defocus tracker to reconstruct the 3D fluid flow.
