A numerical study of microparticle acoustophoresis proves to be a multiphysics problem ideal for using COMSOL. Here's why and how:

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.

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. As an added benefit, by using an equation-based modeling approach and eliminating the need for fundamental coding, you can greatly increase the flexibility in what you can model and reduce the time it would take to set up simulations.

To circumvent the wide length and time scales associated with the typical SAW devices, we employed a perturbation approach resulting in first-and second-order equations (Figure 2), which are then successively Introduction The ability to precisely manipulate fluid and particles at microscales is one of the essential requirements for various lab-on-a-chip applications such as drug diagnostics, chemical synthesis etc.[1] Recently, the nonlinear interaction of surface acoustic waves (SAW) with fluid at microscales has been utilized to achieve this aim. When surface acoustic waves interact with fluid The physics interfaces can all be used with COMSOL Multiphysics, but when tracing charged particles the AC/DC Module is often beneficial because it can be used to model complex alternating or direct current systems and includes more options for Acoustic Solutions using COMSOL Multiphysics There is no reason to learn software programs through trial and error. Even though you may be capable of teaching yourself a new software program, it is a large time commitment and a less efficient way to learn tried and tested methods quickly. 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.
