Phase diagram for the spreading behavior of water drops impacting hot walls observed via high-speed IR imaging

We aimed to derive a phase diagram in the parameter space of wall temperature Tw and Weber number We for the spreading behaviors of water drops impacting a heated sapphire plate. Focusing on hydrodynamic instabilities, we performed drop impact experiments to investigate spreading behaviors with vary...
