Here, g. ref = most refined solution. 9 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.

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.
