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. Keywords: Microparticle acoustophoresis, Acoustophoresis – Particle migration by sound – Acoustic streaming (bulk flow driven at walls) – Acoustic radiation forces (sound scattering off particles) Applications – Ultrasound acoustofluidics – Non invasive manipulation of cells – Lab-on-a-chip Numerical simulations – Design and optimization 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. It is thus thought interesting to embark on investigations into the cause and effects of the negative variation phenomenon.

This will allow us to isolate CTC-mimicking fluorescent beads, then HeLa cells and, eventually, patient tumor cells from whole blood.

heavily dependent on particle size, acoustophoresis also offers separation and positioning in a computational fluid dynamics (CFD) software like COMSOL™.

Starting from an even distribution of 144 particles, the first 10 s of the motion is shown (line segments) as COMSOL analysis of acoustic streaming . and microparticle acoustophoresis .

Once the first-order fields have been established, the equations for time averages of the second-order equations can be solved. So, from here on we shall omit the \langle \cdot \rangle notation for the second-order quantities and whenever they appear in the equation, they will be understood in their time-averaged sense, \langle a_2 ultimately, complicate whole blood acoustophoresis. This will allow us to isolate CTC-mimicking fluorescent beads, then HeLa cells and, eventually, patient tumor cells from whole blood.

The Physics Interfaces and Building a COMSOL Multiphysics Model in the COMSOL Multiphysics Reference Manual A numerical study of microparticle acoustophoresis proves to be a multiphysics problem ideal for using COMSOL. Here's why and how: Examples of this include modeling acoustophoresis and acoustic streaming phenomena when an acoustic field induces a steady flow.
