Maximal spreading of impacting viscoelastic droplets
Orr Avni, Dongyue Wang, Mithun Ravisankar +1
Droplet impact and spreading on solid substrates are well understood for Newtonian fluids, yet how viscoelasticity alone modifies the maximal spreading remains unclear. To identify…

On the early stages of vapor bubble growth: From the surface-tension to the inertial regime
Orr Avni, Eran Sher, Yuval Dagan
This paper presents a new analytical model for the early stages of vapor bubble growth in superheated liquids. The model bridges a gap in current knowledge by focusing on the surfa…
