акустофлюїдика

This article presents the results of numerical modeling and experimental prototyping of an acoustofluidic microchannel structure for the separation of microparticles suspended in a liquid medium. A two-dimensional model was developed to analyze the influence of geometric and physical parameters on the formation of the acoustic field within the microchannel and the efficiency of particle separation.

The article presents the development and analysis of the models of various IDT designs and for the acoustophoretic control of microparticles in of lab chip microchannels. The novelty of the work consists in the development of mathematical models for new configurations of IDT, suitable for focusing, sorting and concentrating of heterogeneous microparticles. The developed models are implemented in the COMSOL environment, which allows the designer to use them for the calculation of the specified IDT structures for real acoustofluidic lab-chips.
