Temperature distribution in an inductively heated CZ crucible

Numerical Simulation for Optical Crystal Growth by TSSG Method

“…Besides the characteristics on details, the overall trend of temperature field distribution shown in Fig. 2, is consistent with in the literature [6,[7][8][9]. For example, there is no Joule heat generated by induced current on the crucible wall.…”

“…In Fig. 2, compared to the literature [8,9], thermal drop between the heating coil and the crucible wall is larger that differences is exacerbated in the crucible for melt flow and heat transfer process. As global temperature field to be a boundary condition, FETSSG professional programs simulate the steady-state process of the melt flow and heat transfer in crucible.…”

“…Numerical simulation of Czochralski crystal growth technology has entered a mature stage. Study groups, under the leadership of Koichi Kakimoto, G.Müller and others respectively established the Cz crystal growth technique of three dimensional computer simulation, domain-wide system [5][6][7][8][9][10]. Application of numerical simulation technology obviously makes great contribution to the promotion of the crystal growth process, in addition to shortening research cycles, reduces research costs.…”

Numerical simulation of a new SiC growth system by the dual-directional sublimation method

“…The electromagnetic field is therefore solved prior to heat transfer calculations to determine the volumetric heat generation Q H (r,z) in the graphite crucible. The magnitudes of C(r,z) and S(r,z) are proportional to the applied coil current density J 0 [14,16]. Therefore, to save computation time, since the angular frequency is given, only one electromagnetic field needs to be simulated for one given furnace shape and coil position.…”

Numerical investigation of induction heating and heat transfer in a SiC growth system

“…It is therefore not necessary to couple the electromagnetic field directly with the heat transfer simulation. So the electromagnetic field is solved prior to the heat transfer calculations to determine the heat generation rate J [10], only one electromagnetic field needs to be simulated for a given furnace configuration and angular frequency ω . A list of physical properties used for the electromagnetic and heat transfer simulation is shown in table 1.…”
