Viscous streaming in 3D and its applications

Particle manipulation plays an important role in numerous fluidic devices involving tasks such as pumping, mixing, separation, sorting, transporting, among many others. When these devices are miniaturized to micro- and milli-meter scale, a second-order fluid effect—viscous streaming—becomes relevant as a label-free and contactless method for such applications. In this thesis, we extend an existing 3D numerical flow–structure interaction (FSI) solver based on Remeshed Vortex Method (RVM) for the simulation and analysis of 3D streaming flows. We validate the accuracy and capability of the solver against a range of 3D streaming problems from single to multiple oscillating bodies, as well as for actuation modes of different sorts and oscillating bodies of unconventional shapes. We then illustrate in a few different settings whereby numerical simulations for viscous streaming in 3D can be used in the context of particle manipulation, from leveraging viscous streaming for inertial particle transport enhancement to probing the fundamental understanding of body shape–flow topology dynamics in streaming flows.
