Three-dimensional magnetic induction model of an octagonal edge-defined film-fed growth system

On the Creation of a Stable Drop‐Like Static Meniscus, Appropriate for the Growth of a Single Crystal Tube with Prior Specified Inner and Outer Radii

“…Later, the heat flow in a tube growth system was analyzed in [10][11][12][13][14][15][16][17][18][19] . The state of the arts at the time 1993-1994, concerning the calculation of the meniscus shape in general in the case of the growth by E.F.G.…”

“…These limits are represented for n ∈ 1; 1.1 in Figure 2. The computations were performed in MathCAD V. 13 for z e R ge 0, z e R ge − tan α c and different p e . The obtained outer radii r e versus p e are represented in Figure 3, which shows that the desired outer radius r 1 Actually, as it can be seen on the same figure, for p e 149.7 Pa , we can obtain also a second outer radius r 2 e 3.8 • 10 −3 m , which is not anymore in the desired range R gi R ge /2, R ge .…”

The effect of the pressure on the static meniscus shape in the case of tube growth by edge-defined film-fed growth (E.F.G.) method

“…Later the same model was used to determine the critical parameters controlling silicon carbide precipitation on the die wall. Rajendran et al [7] also developed a three-dimensional (3D) magnetic induction model for an octagonal E.F.G. system.…”

An advanced multi-block method for the multiresolution modelling of EFG silicon tube growth

“…In the second method, attention is paid to certain transport phenomena. A typical example is the work of Rajendran et al (1991Rajendran et al ( , 1993Rajendran et al ( , 1994, in which the electromagnetic field is of special concern. An axisymmetric finite element model predicting magnetic and thermal fields was proposed to study the magnetic and temperature fields in an inductively heated EFG furnace (Rajendran 1991).…”

“…Later, the same model was used to determine the critical parameters controlling silicon carbide participation on the die wall during silicon tube growth (Rajendran 1993). More recently, Rajendran et al (1994) extended their model to three dimensions and investigated magnetic induction and its effects on tube thickness. In the third category, research focuses on the entire furnace.…”
