By using the Oseen approximation of the Navier-Stokes equation, the linear stability analysis and the solvability criterion, one determines a scaling factor σ=2 d0DT /ρ2V as a function of the velocity of the forced flow and the impurity concentration in the melt in the three-dimensional model. The criterion obtained rallies analytic results for dendrite growth under forced convection in a pure system [1] and dendrite growth in a stagnant binary system [2].6 pagesPDFenUniversity of PretoriaHeat transferHEFATFluid mechanicsThermodynamics8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics 2011Forced flow3d dendritic growthBinary systemsTheoretical studyOseen approximationPresentation
