Magnetism in Microfluidics: Computational Fluid Dynamics Simulations, Mixing, Transport, and Control of Fluids and Particles at Micro Scale
Abstract
Computational fluid dynamics (CFD) simulations of a range of problems that cover redox electrochemistry-based magnetohydrodynamics (MHD) are presented. Models for redox electrochemistry and MHD, and details of the solution algorithms and solution implementation are described. Suggestions to improve existing empirical mass transfer-limited current models are included. The use of larger number of electrodes and more complex potential switching schemes than used in previous investigations is shown to improve mixing quality. We also report CFD simulations of rotational dynamics and lateral migration of a paramagnetic microparticle of an elliptic shape in a simple shear flow and plane Poiseuille flow under a uniform magnetic field. The parametric simulations offer insights of a novel particle separation method that utilizes magnetic torques due to uniform magnetic fields different from conventional methods using magnetic forces.
