Evaporation of bang xxl switch duo 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.Direct numerical simulations were performed, showing a strong relation between flow to the film inside the cavity and bubble growth at the pore.Additionally, a model was created with a novel modeling approach which is based on solving the Young-Laplace equation.
From the model characteristic nondimensional heelbo website parameters can be obtained and the influence of geometry variations on hydrodynamics can be studied.
