Steady State Vapor Bubble in Pool Boiling
Boiling, a dynamic and multiscale process, has been studied for several decades; however, a comprehensive understanding of the process is still lacking. The bubble ebullition cycle, which occurs over millisecond time-span, makes it extremely challenging to study near-surface interfacial characteristics of a single bubble. Here, we create a steady-state vapor bubble that can remain stable for ho...
متن کاملSIMILARITY OF VAPOR AND Gf.S BUBBLE GROWTH
The bubble growth problems in both boiling and electrolysis are nondimensionalized in such a way as to make them identical. Nonuniformity of the initial temperature and the possibility of a measure of subcooling in the ambient liquid are considered. The nondimensiona/ization makes it possible to compare gas-bubble growth theory with vaporbubble growth data. Such a comparison is made for the dat...
متن کاملCFD Simulation of Condensing Vapor Bubble using VOF Model
In this study, direct numerical simulation for the bubble condensation in the subcooled boiling flow was performed. The main goal was to develop the CFD modeling for the bubble condensation and to evaluate the accuracy of the VOF model with the developed CFD modeling. CFD modeling for the bubble condensation was developed by modeling the source terms in the governing equations of VOF model usin...
متن کاملDynamics of a vapor bubble near a thin elastic plate
Numerical and experimental results show that during the collapse phase of a vapor bubble near a rigid boundary, in the absence of strong buoyancy forces, a liquid micro jet is developed on the side of the bubble far from the rigid surface and directed towards it. Numerical and experimental results also show that, in the case of a bubble near a free surface, during the collapse phase of the bubb...
متن کاملCondensation of a vapor bubble in submicrometer container.
Condensation of a spherically symmetric submicrometer size vapor bubble is studied using diffuse interface hydrodynamic model supplemented by the van der Waals equation of state with parameters characteristic for argon. The bubble, surrounded by liquid, is held in a container of constant volume with temperature of the wall kept fixed. The condensation is triggered by a sudden rise of the wall t...
