Abstract
To explore the effect of Bond number on the freezing characteristics of water droplets, experimental and modeling studies are carried out. The effects of contact angle and cold plate temperature are analyzed. The results show that: 1) When the Bond number is larger than 1, the freezing characteristics of sessile and pendant water droplets are significantly different, and the freezing profile of pendant water droplets is high and the freezing time is long. As the Bond number increases, the difference between them increases. 2) With the increase of contact angle, the freezing profile of water droplets becomes high and the freezing time increases, and the difference of freezing characteristics between sessile and pendant water droplets becomes more obvious. The freezing profile is independent of the cold plate temperature. 3) The correlation formula of freezing time calculation is proposed, and the prediction error is less than 20%. The research has guiding significance for the optimization of anti-icing and de-icing technology.
