고온의 원형 실린더에 충돌하는 액적의 유동 가시화
2016
Water droplets impinging onto a heated circular cylinder were visualized using a high speed camera. Cylinder diameter was chosen as 6 ㎜ to match with the droplet diameter. Heights were in the range of 40~160 ㎜ to change Weber number. Surface temperatures of the circular cylinder was ranged from 25℃ to 300℃. Four different boiling phenomena were observed according to Weber numbers and surface temperatures. A characteristic map of dynamic behavior was obtained with respect to Weber numbers and surface temperatures.
