Sunil Mehendale (MMET) has co-authored an article accepted for publication in the Journal of Heat Transfer Research.
The article is titled “Visual Study of the Freezing Process of a Water Droplet on a Horizontal Copper Plate.”
In this study, based on the droplet shape analyzer, the freezing process of droplets has been studied experimentally. The effects of the substrate temperature, ambient relative humidity, and volume of droplets on the freezing process were analyzed. The ambient relative humidity and substrate temperature influenced the degree of supercooling. With decreasing substrate temperature, a critical value of supercooling was found to exist. The effect of droplet volume on supercooling time was found to be non-monotonic. With increasing droplet volume, the supercooling time first decreased first and then increased.
This research has potential applications to ice control and mitigation, and de-icing technologies.
