【Abstract】 This paper presents a study about the mixing of magnetic nano-fluid and deionized water in a Y-shape micro-channel. The effect of static magnetic field (magnetic flux density 40 Gs) on the mixing is investigated at the case of Re=0.5~4, and the volume fraction respectively from 0.38% to 1.54%. The results show that the mixing length is largely reduced by the static magnetic field. And the effects of Re and the volume fraction on the mixing length are analyzed.更多还原
