摘要

On the physical point of view, the dewetting phenomenon is governed by the Young-Laplace capillary equation through the Laplace (La) and Bond (Bo) non-dimensional numbers. Other relevant parameters are the contact angle of the liquid on the crucible wall, θ_c, and the growth angle of the solidified material, α_e. In practice two different cases, θ_c+α_e< 180° and θ_c+α_e> 180°, should be considered, as they lead to different behaviors.rnFor studying the dependence of the crystal-crucible gap (e) on the main parameters of the process, the non-dimensional Young-Laplace equation has been solved numerically in the axi-symmetric case and for various values of the parameters, the results are presented in term of abacuses.rnThese calculations allowed plotting a diagram giving the values of Laplace's number as a function of the crucible radius, that furthermore fulfill the capillary stability criteria of the crystal diameter.
