バッフルを用いたT型マイクロミキサーにおける二液混合

抄録

This study was performed to numerically simulate two-liquid flows in a micro T-mixer with baffle. The baffle length and setting angle were varied to investigate their effect on the mixing performance. The mass conservation, alpha diffusivity and momentum conservation equations as the governing equations are used to mathematically model the problem, and a transient solver twoLiquidMixingFoam for mixing of 2 (two) incompressible fluids was used to solve the governing equations. As a result, the length and setting angle of the baffle shown a significant influence on the mixing performance, and a good mixing efficiency can be obtained for a baffle of length l_b=0.07mm at a setting angle of θ_b=30o and at a varying pitch.
