Evaporation of thin liquid films inside reentrant cavities occurs in several boiling processes where enhanced surfaces are utilized. In this work. evaporation from a single reentrant cavity with an additional thin channel is studied. The channel allows the backflow of liquid from the pool into the cavity during bubble growth. https://www.roneverhart.com/Apple-Watch-Ultra-2-GPS-Cellular-49mm-Titanium-Case-with-Blue-Black-Trail-Loop-S-M-MRF53LL-A/
