Abstract
In this study, the dynamic characteristics of water droplets impinging on a heated cylinder were investigated using a high-speed camera regarding the diameter ratios between droplet and cylinder. Water droplets generated by a needle in the range of 2.5 mm to 5.0 mm in diameter were impinged onto a cartridge heater with surface temperature of 25 °C and 300 °C. The diameter of the cartridge heater was 6.0 mm. The recording rate of the high-speed camera was set to 10,000 Hz, and the Weber number was controlled from 17.4 to 217 by adjusting the free-fall height of the water droplets. As a result, the dynamic characteristics of water droplets impinging on cylinder were different depending on the diameter ratio and Weber number. In the high-temperature region, the water droplets were detached from the cylinder after the impingement by Leidenfrost effect. Under conditions of low Weber number and low diameter ratio, the water droplets were rebounded in the opposite direction of the impingement, maintaining its shape. However, as the Weber number increases, the water droplets impinging on cylinder were broken-up and detached by the Leidenfrost effect regardless of the diameter ratio. This study is expected to be utilized to determine the dynamic characteristics of droplet, and be applied such as phenomenon analysis of the heat transfer and cooling.
