Abstract
We propose a new micromixing process utilizing gas-liquid free interface. This new process enhances mixing by narrowing and winding flow due to the existence of bubbles. Moreover, because shear stress does not work on gas-liquid free interface, this process will reduce pressure drop. Through flow experiment and CFD analysis, we compared the mixing performance of the new micromixer with that of conventional Y flow micromixer. The experimental result proved that the new micromixer can promote more mixing than Y flow micromixer. Furthermore, the CFD analysis revealed that the new micromixer can reduce pressure drop.
