A numerical study of microparticle acoustophoresis driven by acoustic radiation forces and streaming-induced drag forces Peter Barkholt Muller,a Rune Barnkob,b Mads Jakob Herring Jensenc and Henrik Bruus*a Received 28th May 2012, Accepted 18th July 2012 Veryst Engineering, LLC provides premium engineering consulting services. 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.

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. EXPERIMENTAL COMSOL modeling software was used to create a large number of microfluidic designs for simulation, an example of which is shown in Figure 1.

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.

To circumvent the wide length and time scales associated with the typical SAW devices, we employed a perturbation approach resulting in firstand second-order equations (Figure 2), which are then successively solved using appropriate boundary conditions (Figure 1).

Examples of active technologies are acoustophoresis, thermophoresis, for U and U were obtained by simulating the fluid flow by COMSOL Multiphysics, 

2013-03-07 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.
