Trapaga and Szekely 515 conducted a mathematical modeling study of the isothermal impingement of liquid droplets in spray processes using a commercial CFD code called FLOW-3D. Their model is similar to that of Harlow and Shannon 397 except that viscosity and surface tension were included and wetting was simulated with a contact angle of 10°. In a subsequent study, 371 heat transfer and solidification phenomena were also addressed. These studies provided detailed... 

Szekely and Carr 58 have studied the heat transfer between the walls of a cyclone and a gas-solid suspension, and have shown that the mechanism of heat transfer is quite different from that occurring in a fluidised bed. There is a high rate of heat transfer directly from the wall to the particles, but the transfer direct to the gas is actually reduced. Overall, the heat transfer rate at the walls is slightly greater than that obtained in the absence of the particles. 

Previous studies of direct reduction on iron ore pellets have been reviewed by Themelis(1), Bogdandy(2) and Huebler(3). Work on reduction by mixtures has been reported by Szekely(4) and Hughes et al(5). Modelling studies on countercurrent moving bed systems have been reported by Spitzer(6) for isothermal reduction in hydrogen, by Miller(7) for non-isothermal reduction in carbon monoxide and more recently by Tsay et al(8) and Kam and Hughes(9) for C0/H2 mixtures. However, since iron is known to be a catalyst for the water gas shift reaction, this reaction will influence the gas composition and therefore the extent of reduction. None of the previous analyses have considered this aspect and the objective of the present paper is to account for the overall reduction by inclusion of this reaction.

A number of studies have used the grain model as the basis for comparison with experimental data. For example, Szekely and Evans studied the reduction of nickel oxide pellets with hydrogen. Their grain model analysis considered the effects of external mass... 

As stated in the beginning of this section, there have been quite a number of versions of the gas-solid reaction analysis. Further detail has been provided by Bischoff, Luss, and Yoshida, et al. [K.B. Bischoff, Chem. Eng. Sci., 46, 7111 (1963) D. Luss, Can. J. Chem. Eng., 46, 154 (1968) R. Yoshida, D. Kunii and F.J. Shimizu, Chem. Eng. Japan, 8, 417 (1976)]. A more detailed model, considering the granular nature of most porous solids, has been given by Szekely and coworkers [H.Y Sohn and J. Szekely, Chem. Eng. Sci., 25, 1091 (1970) J. Szekely and J.W. Evans, Chem. Eng. Sci., 27, 763 (1972) 29, 630 (1974) J. Szekely, J.W. Evans, and H.Y. Sohn, Gas-Solid Reactions, Academic Press, New York, NY, (1976)]. Some more studies of a similar nature, but with application to catalyst regeneration, will be given in the next section.
