Non-aligned bilayer square-wave bend microchannel for mixing

초록

A numerical study has been conducted on a modified design of square-wave bend microchannel to enhance mixing performance. The channel domain is divided into two layers of equal heights. The position of the layers is non-aligned in the lateral direction to construct a bilayer bend channel. The idea was to modulate the dean vortices formed in the bends. The bilayer bend channel shows enhanced mixing performance compared with a simple bend channel. Unlike a simple bend channel, a bilayer bend channel exhibits the formation of multiple vortices at different positions. This study has employed three values of offset positions at different Reynolds numbers.
