Molten metal droplet impingement and subsequent solidification phenomena in both inert and non-inert gas environment exist widely in various industrial applications. Exposing a molten droplet to air allows to form an oxide layer on the droplet surface which greatly influences the thermophysical properties of the droplet. While previous studies demonstrated the influence of oxide layer on the spreading dynamics, understanding of the impact dynamics is still missing when solidification is involved. To address this issue, in the present study, high-speed imaging was used to determine the interaction dynamics and solidification behaviour of a molten droplet of three different compositions onto a solid surface over a range of Weber numbers (We < 150) in an open atmosphere. Two distinct outcomes were noted – (1) rebound and (2) disintegration demarcated by a critical Weber number. Upon impingement, each droplet exhibited periodic spreading and recoiling behaviour which was subsequently

just the cancel culture and all the anti-masculinity stuff that is going on i think just basic sense of fairness that people are recoiling from. it s not fair, and it s pragmatic. speak to that as it relates to this breaking news tonight. i think there is part of our human nature, laura, that demands the truth, we as human beings, the things that make us different from animals is we relate to one another by actually telling the truth to each other. we live in a moment where the government repeatedly hides from us the truth about the over in of covid-19, the hunter biden laptop story, and the truth of that matter. the truth about what happened on january 6th and now the truth about what s really behind these politicized indictments. i think we the people are at a place where we just want the government to tell us the truth. tomorrow, laura, i m going to national, speaking of young people, calling, this is prescheduled, to release that
culture and all the, you know, anti-masculinity stuff that s going on, i think just the basic sense of fairness. that people are recoiling from. it s just not fair. and it s pragmatic. speak to that as it relates to this breaking news tonight. i think there is part of our human nature, laura, that demands the truth. we as human beings, the thing that makes us different from animals is that we relate to one another based on actually telling the truth to one another. we now live in a moment where the government repeatedly hides from us the truth about be it the origin of covid-19. be it the hunter biden laptop story, and the truth of that matter. the truth about what happened on january 6th, and now the truth about what s really behind these politicized indictments. i think we, the people, are at a place where we just want the government to tell us the truth. tomorrow, laura, i m actually going to nashville, speaking of young people, calling, this is prescheduled, calling on them to
personal space. this is weird. what is he doing? literally nibbling her. it sounds so weird. i try to be charitable watching that video, but i see the old man thing here, i am trying to do that half scary half cute thing to a child. you would not see the horror on her face. she is recoiling. the part where i go come on man, he did the sniffing thing one more time. he did smell her hair on the way out. you d still think he is a bit weird. it is not some random person. she gets her phone out, the mother.
