Abstract: This paper deals with the identification of transition convective regimes in liquid metals by means of the numerical simulation of the melting of solid spheres in uniform flow baths. The cases of forced convection with ''aiding'' and ''cross-flow'' natural convection are investigated. The fluids studied have Prandtl numbers between 10^-3 and 10¹. A three dimensional mathematical model has been developed using the SIMPLER algorithm to study the melting of a spherical addition initially at room temperature subjected to a uniform flow of liquid metal. The melting times are obtained as a function of the bath temperature and velocity. The model is validated against experimental results in water and liquid Aluminium, showing good agreement with the existing data.
