Eureca 1 AMF 117 experiment: An analysis of thermal and solutal transfer during the crystal growth of CdTe by the THM process

Fluid phase motions and their interactions with single crystal growth processes are described. Within the context of the growth experiment of CaTe by THM (Traveling Heater Method), the concentration driven convection is integrated with the thermal convection. A numerical method previously tested for thermal natural convection is extended to the thermosolutal convection case. The problem is described by the Navier-Stokes and continuity equations coupled with two convection diffusion equations. Two kinds of boundary conditions are being introduced: active walls, e.g., solid fluid interfaces, and non active walls e.g., enclosure walls. Results of the determination of characteristic dimensionless parameters are presented in different configurations.
