AcoDyn: Efficient computer simulations of acoustically propelled microparticles — •Adrian Paskert and Raphael Wittkowski — Institut für Theoretische Physik, Center for Soft Nanoscience, Universität Münster, 48149 Münster, Germany

For future applications in science and engineering, active microparticles have great potential. Acoustically propelled microparticles are particularly advantageous for medical applications because they operate well within medically safe intensity ranges and are generally considered biocompatible. However, due to the complexity of the flow fields generated around these particles and the high computational cost of direct computer simulations even for simple 2D particle geometries, the theoretical understanding of the particles’ propulsion and dynamics is still very limited. In this talk, we will give an overview of how these particles can be simulated efficiently to enable the numerical study of complex 3D particles. Moreover, our novel software solution AcoDyn will be presented, along with key results we have obtained through its application.
