Numerical simulation of the detachment of bubbles from a rough surface at microscale level

In this paper nucleate boiling is studied at microscale level in two dimensions focusing on the influence of the cavity size and density on the growth and detachment of a single bubble. Furthermore the interactions of bubbles detaching from two neighbouring nucleation sites are studied in details.

► Bubble detachment from cavities of a heated plate is studied in microscale.
► Vapor generation rate depends on the geometrical parameters of the cavity.
► Neighbouring cavities can deactivate each other or freezing the nucleation.
