MAMatteo Antuono SMS. Marrone ACandrea colagrossi

Key Points

The central aim is to analyze the coalescence and break-up phenomena of viscous drops with surface tension effects.
Utilized the RHOD-SPH scheme for numerical analysis.
Applied Navier-Stokes equations to describe fluid behavior.
Conducted energy balance analysis during drop interactions.
Identified critical points during coalescence and break-up processes.
Demonstrated the influence of surface tension on drop behavior.
