가열된 회전 표면 위에 충돌하는 액적의 변형 특성 및 거동 추적 = Deformation characteristics and trajectory tracking of a droplet impacting on a rotating heated surface

다국어 초록 (Multilingual Abstract)

Interaction between a droplet and a heated rotating surface occurs in a variety of industrial applications such as spray cooling systems. We investigate the spreading and movement characteristics of the impacting droplet on a heated rotating surface by adjusting the droplet impacting velocity, droplet diameter, substrate surface movement velocity, and the substrate surface temperature. It is shown that the spreading behavior of the droplet drastically changes as the droplet detaches from the surface when the surface temperature exceeds the Leidenfrost temperature. Meanwhile, above the Leidenfrost temperature, the droplet retains a spheroidal shape and represents a peculiar bulk movement above the rotating surface.
