Description
Summary:Snow and ice accumulation on surfaces presents significant safety and efficiency challenges across various industries, necessitating the development of effective mitigation strategies. In this study, the dynamics and energy dissipation of natural snowflakes impacting superhydrophobic surfaces (SHS) were explored using high-speed imaging and a novel image processing method. The size, velocity (impact and bounce), and contact time of natural wet snowflakes were quantitatively analyzed, identifying two primary impact outcomes: bouncing and fragmentation. The analysis focused on bouncing to study the coefficient of restitution (COR) of snowflakes. It was found that small snowflakes (
