quantified using the COMSOL particle-tracking scheme. The model shows how the acoustopho-retic particle motion changes from being domi-nated by streaming-induced drag to being domi-nated by radiation forces as function of particle size, channel geometry, and material properties. Keywords: Microparticle acoustophoresis,

Driven by our mission — “Engineering through the fundamentals” — we use our grounded knowledge of mechanics, physics, materials science, manufacturing, and computational methods to produce practical and useful results that meet our clients’ needs. This webinar is geared toward attendees who have little to no experience with COMSOL Multiphysics® who would like a hands-on introduction to the software. It is also appropriate for those who are interested in learning how to set up computer simulations for problems in electrophoresis using this … Similarly, experiments with silicon-glass devices show a noticeable improvement in acoustophoresis of 20-μm silica beads in water when asymmetric devices are used. (COMSOL AB, Stockholm, COMSOL, Kongens Lyngby, Denmark Published in 2012 We have simulated the ultrasound-induced acoustophoretic motion of microparticles suspended in an aqueous solution. The full first-order thermoviscous acoustics equations have been implented on a rectangular microfluidic 2D domain excited with an ultrasound field tuned to resonance near 2 MHz. 2013-03-07 · Our microparticle acoustophoresis paper clearly showcases how COMSOL can be used to solve and couple virtually any physical phenomena described by partial differential equations and a system of ordinary differential equations.

Acoustic radiation is an acoustophoretic phenomenon, that is, the movement of objects by sound. One interesting example of this force in action is the acoustic particle levitation discussed in this previous blog post. Today, we shall examine the nature of this force and show how it can be computed using COMSOL Multiphysics.
