외부 가스 유동에 의한 미소 액적 내부 유동 제어 및 가시화

We conducted experimental visualization and numerical simulations of flow inside a droplet subjected to an external gas flow. The purpose of this study is to confirm a flow-control method provided by agas flow over a droplet, which may be used in the enhancement of the semiconductor performance, in the case where the semiconductors are manufactured by the principle of inkjet printing. Our ultimate target is to remove the coffee-stain effect and make the osc align in the direction of current in between a pair of micro electrodes.
