Journal ArticleDOI
Thermal-capillary analysis of Czochralski and liquid encapsulated Czochralski crystal growth: I. Simulation
Jeffrey J. Derby,Robert S. Brown +1 more
TL;DR: In this article, finite element analysis of the Czochralski (CZ) and liquid encapsulated (LEC) crystal growth processes based on a thermal-capillary model which governs the heat transfer in the system simultaneously with setting the shapes of the melt/solid interface, the melt and encapsulant menisci, and the radius of a steadily growing crystal.
Journal ArticleDOI
Heat transfer in vertical Bridgman growth of oxides - Effects of conduction, convection, and internal radiation
Simon Brandon,Jeffrey J. Derby +1 more
TL;DR: In this article, internal radiation and heat conduction during the vertical Bridgman growth of a YAG-like oxide crystal, where transport through the melt is dominated by convection and conduction, is also noted to be conducted through ampoule walls via natural convection, and enclosure radiation.
Journal ArticleDOI
Heat transfer and interface inversion during the Czochralski growth of yttrium aluminum garnet and gadolinium gallium garnet
Qiang Xiao,Jeffrey J. Derby +1 more
TL;DR: In this article, computer-aided simulations are performed using an integrated process model for the Czochralski (CZ) growth of yttrium aluminum garnet (YAG) and gadolinium gallium garnet(GGG).
Journal ArticleDOI
Permeability calculations in three-dimensional isotropic and oriented fiber networks
Triantafyllos Stylianopoulos,Andrew Yeckel,Jeffrey J. Derby,Xiao Juan Luo,Mark S. Shephard,Edward A. Sander,Victor H. Barocas +6 more
TL;DR: It is concluded that a weighted combination of drag coefficients for spatially periodic arrays of fibers could be used as a good approximation for fiber networks, which implies that the effect of the fiber volume fraction and orientation on the permeability of fiber networks are more important than theeffect of local network structure.
Journal ArticleDOI
An integrated process model for the growth of oxide crystals by the Czochralski method
TL;DR: In this paper, a comprehensive model for the Czochralski growth of oxide crystals is developed which integrates analyses of global heat transfer, transport phenomena in the crystal and melt, and the interfaces of the growth system.
