Abstract
The influence of gravity on water droplet freezing on a cold solid surface has been investigated in this study. Experimental results over a range of Bond numbers, for both pendent and sessile droplets, show that gravity can significantly influence the freezing processes via shaping the initial droplet. Despite the significant difference in the initial droplet shape, some remarkable similarities have been found for pendent and sessile droplets at small and large Bond numbers. The final height of a frozen droplet is found to be proportional to its initial height.
