E-mail: isabellamas@udc.esAbstract. The present paper presents a tri-dimensional CFD (Computational Fluid Dynamics) model to investigate the fluid flow around bubbles attached to heated walls. Transient solutions of the governing field equations in a domain containing the bubbles and the surrounding liquid have been obtained. The nucleation, growing and detachment processes have been analyzed. Concerning the software, the open source OpenFOAM has been used. Special attention has been given to the bubble detachment diameter. Two mechanisms have been considered as physically related to the detachment: surface tension and buoyancy. As expected, it has been verified that the bubble detachment diameter depends on the contact angle, operating pressure and properties of the fluid. Several fluids have been considered (water, R134a, ammonia and R123), as well as several operating pressures (between 0.1 and 10 bar) and contact angles (between 10 and 80º). It has been concluded that the detachment diameter depends strongly on the contact angle and fluid properties and slightly on the pressure. A correlation for the bubble detachment diameter has been developed based on the obtained numerical results. Data from this expression compare reasonably well with those from other correlations from the literature.

In this investigation, the solidification, phase change, melting and heat transfer phenomenon from the outer surface of the solid sphere (stainless steel) having different dimensions were analyzed. Liquid nitrogen has been used to cool the sphere at a cryogenic temperature up to-192 ℃, then dipped the sphere inside a phase change material (brine solution NaCl-H2O of different concentration at ambient temperature) and study the solidification and melting phenomenon. The thickness of ice formation at the outer surface of a sphere is measured for different concentration of brine solution. Variation of ice thickness is also measured for different concentration at different time intervals. It is interesting to note that the time duration of solidification of ice and melting is depending upon the concentration of the solution. Melting behavior of ice is discussed for different concentration.
