Abstract

This paper presents a numerical investigation of the mixing performance of two hybrid passiveactive micromixers subjected to an acoustic field. The study employs the Generalized Lagrangian Mean (GLM) theory and the convection-diffusion equation to analyze concentration profiles within the micromixers, providing a comprehensive assessment of their performance. Perturbation theory is employed to solve the equations of zeroth-, first-, and second-order, resulting in the determination of the final flow velocity from the zeroth- and second-order solutions. Notably, the study incorporates a non-zero background laminar flow to explore the interaction between acoustic waves and a moving laminar flow. The findings reveal that while the presence of sharp-edge structures on the channel walls significantly enhances mixing quality, this improvement is not observed that much when rectangular structures.
