摘要

The concept of macro scale synthetic jets has been applied to the low Reynolds number channel flows associated with biosensor microfluidics. The current numerical investigation utilizes a hybrid approach of the lattice Boltzmann method for flow field computations and the convection-diffusion equation for passive scalar transport. The study presents results for various synthetic jet geometries, jet inlet conditions, scaling issues and Reynolds numbers. The results indicate limited effects due to synthetic jet cavity-slot geometry and that the synthetic jet imparts momentum to the channel flow thus enhancing fluid mixing.
