“…Experimental evidences [9,[16][17][18] indicate that the major resistance to heat and mass transfer lies within the bubbles and, hence, the dispersed phase modelling has drawn considerable attention. As a result, many models for describing coupled heat and mass transfer in bubbles have already been elaborated, either for the formation [19][20][21][22][23][24] or the ascension stage [4][5][6]8,9,[25][26][27].…”

“…The ratio of the maximum liquid droplet formed to the jet diameter is related to the Bond number based on the jet diameter, jet Reynolds number and the jet Weber number. The rise rate of vapor bubbles in a liquid medium and the heat transfer between rising column of vapor bubbles and the bulk liquid can be found in chemical engineering literature (examples are Perry & Chilton, 1973;Iguchi, Morita, Tokunaga, & Tatemichi, 1992;Komaro & Sano, 1998).…”

The use of combustion synthesis to prepare ceramic-metal composites containing alumina and metal as well as carbide or boride was discussed by Feng et a1. l ,2 The combustion synthesis of Nb-Al intermetallics and composites containing a NbB reinforcement phase was studied. 3 Metal-ceramic composites were also prepared by the same technique. 4 A number of intermetallic compounds were produced from a mixture of metals and metal oxides 5 or from a mixture of constituent metals 6 through the use of combustion synthesis.Okabe et a1.7 investigated the fundamental aspects of synthesizing fine niobium aluminide powders from Nb 2 0 3 and aluminum powder by calciothermic reduction. A mathematical model for laser cladding by powder injection was forwarded. 8 PYROMETALLURGY Kinetics and MechanismsSohn and Aboukheshem 9 experimentally verified the rate-enhancing effect of pressure cycling on gas-solid reactions using the hydrogen reduction of porous nickel oxide pellets. Proctor et a1.10 investigated the reduction of iron oxide pellets in a CO-COz-Hz-Hp mixture. A nonisothermal technique was used to evaluate the kinetics of hydrogen reduction of molybdenum oxides. 11 The oxidation of copper concentrate particles during their downward flight in an N Z -0 2 gas stream was investigated experimentally.12 Bonsack13 studied the reaction of ilmenite with FeC1 2 vapor, producing TiCl 4 and metallic iron.The sequence of carbo thermic reduction reaction of ilmenite was established using the M6ssbauer effect. 14 The kinetics of the carbothermic .reduction of niobium pentoxide and pyrochlore concentrate in the presence of iron were studied in an argon arc plasma. ls Kale et al.I 6 determined the kinetics of carbothermic reduction of phosphogypsum. Langlais and Harris l7 extracted strontium from strontium carbonate by aluminothermic reduction.The kinetics of decarburization of iron by oxygen 18 and water vapor 19 were measured. Fruehan zo reviewed the fun-40 damentals of the reaction of FeO dissolved in slag with the carbon dissolved in iron and with coal char. The process of slag forming was also discussed. The kinetics of the reduction of FeO in slag by Fe-C drops21 and by graphitell were determined. Kulunk and Guthrie2 3 studied the kinetics of the removal of sodium from aluminum and alUminum-magnesium melts by chlorine gas. The rates of iron desulfurization using calcium carbide and lime-magnesiummixtures 24 and by CaO-CaFz based fluxes 25 were examined and reported. Phase Equilibria and ThermochemistryAtomic models of liquids and amorphous oxides of the CaO-SiOz system were constructed by continuous statistical relaxation and molecular dynamic model methods. Z6 The feasibility of evaluating the thermodynamic properties of the melts from structural data was also discussed.Sommerville and Masson z7 described how the optical basicities of individual anions in slags may be calculated. The ionic structure of cryolite-based melts was evaluated based on vapor pressure data. 2s An improved analysis of the carbonoxygen equilibrium in liqU...
