چکیده مقاله:
The current study involves conducting a two-dimensional numerical simulation to investigatethe process of a single rising bubble condensation in a subcooled stagnant liquid under the effectof a magnetic field. To simulate the condensation phenomenon, the energy equation andTanasawa mass transfer model, along with appropriate source terms, are incorporated into theOpenFOAM solver utilizing C++ coding. The surface tension between vapor-liquid phases isconsidered using the Continuous Surface Force (CSF) method, and the Volume of Fluid (VOF)model has been used to track the interface of the two phases. The numerical findings wereinitially compared to the experimental and numerical results, indicating good agreement. Thenumerical findings demonstrated that for a bubble with an initial diameter of ۱.۰۰۸mm, thetendency to deform from a spherical shape is negligible in the absence of a magnetic field, andit retains a nearly spherical shape while its size decreases. Furthermore, the magnetic fieldcauses elongation of the bubble along the magnetic field lines. The smaller the diameter of thebubble (۱.۰۰۸mm), the faster the vertical magnetic field increases the condensation process.Conversely, for larger bubbles (۴mm), the presence of the magnetic field causes them tocondense and disappear more quickly.
