Abstract: Present paper deals with numerical simulation of boiling heat transfer around a heated wire. It reports nucleation of bubble, thickening of film and as a whole breaking and making of interfaces. Volume of fluid based finite volume discretization is adapted for modelling mass, momentum and energy equations. Similar to Nukiyama’s experiment a cylindrical wire has been taken as source of heat. Liquid water at normal atmospheric pressure is considered as working fluid in the simulations. Continuous supply of heat from constant temperature wire caused film boiling and nucleation after sufficient growth of film thickness. In absence of nucleation site, generated bubbles are formed randomly from the upper surface of the wire. Complete life cycle of the bubble and formation of bubble cloud over the wire has been observed. From simulation, it has been observed that with increase in heat flux bubble release rate increases. Similar has been also concluded by Nukiyama in his famous boiling experiment. © 2018 by the authors of the abstracts.
