Abstract

Recently, we reported a sharp-edge-based acoustofluidic micromixer [1], as well as a numerical investigation of the flow patterns around sharp edges [2]. Here, we extend our finite element numerical model, qualitatively validated by experimental results, to include the convection-diffusion equation and allow the presence of a background flow for investigating acoustic streaming based mixing phenomena. We utilize a perturbation approach in conjunction with the convection-diffusion equation to characterize the effects of various geometrical and operational parameters for optimizing the performance of sharp-edge-based acoustofluidic micromixer.
