“…The discontinuous increase in conductivity for solutions 4 and 5 corresponds to the solid/liquid interface. Figures (3-11) thru (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) The variation of the power density with radial position. Similar to the electrical conducitivity, the discontinuous increase for solutions 4 and 5 correponds to the solid/lquid interface.…”

“…It is possible to identify at least three ways to achieve thermal switching via Figure ( The explanation to this behavior is found in Figure (3 Such a comparison is illustrated in Figure (3-14) for a Figures (3-15) thru (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) Surface temperature as a function of coil current squared for different values of skin depth. The instability at melting is a sensitive function of this parameter.…”

“…The power density within the material being induction The integral of the power density over the cross-sectional area of the sample equals the the total eddy current heating (power per unit sample length) within the sample. An analytical expression for this integral is given below and is shown in Figure (3-2) as a function of skin depth:4-2 (Pv 2) 2 berO (/2/2) bero' 6/2/21 + bein (n/7} beiQ' (gr#/2) 8 ber02 0/3/23 + bei02 (1/2/2 1(3)(4)(5)(6)(7)(8) From this expression for the eddy current heating it is possible to deduce the relative ease with which d particular material can be induction heated. An analysis of this curve…”

“…In general, these studies apply to solidification of semiconductors and cannot be generalized to represent the behavior of oxide crystals. The earliest investigations of the effect of radiation on nonopaque crystals is due to Viskanta and coworkers 1969 and O'Hara et al;1968, Viskanta;. In these studies, the formidable general problem is reduced to a one-dimensional analysis of steady state conduction and radiation heat transfer as it occurs between two partially transparent media in intimate thermal contact.…”

JiEi KVAPIL, J. KUBELKA, R. VADURA Monokrystaly Turnov, Czechoslovakia Temperature Distribution in Growing Semi-Transparent Crystals (I). TheorySimplified analytical and computational solutions of the temperature distribution in crystals grown by Czochralski method including the temperature difference on the liquid/solid interface a r e given. The model used is based on experiments with oxide crystals with me€ting points above 2000 K. Computational solution was more extended because it enables to calculate actual temperature distribution with a relat ive ly small error. E s wird eine analytische und eine Rechendethode filr die Temperaturverteilung in einem nach der Czochralski-Methode gezuchteten Kristall angegeben. Der Temperaturunterschied mischen Kristall und Schmelze wird ebenfalls errechnet und das Modell auf Experimente mit hochschmelzenden oxydischen Kristallen begrundet. Die analytische Methode ist nur fur eine Abschatzung geeignet, wtihrend die Rechenmethode e s ermoglicht, die wirkliche Temperaturverteilung zu erkennen.
