The method of chemical transport has gained considerable attention in the research fields of crystal growth, chemical engineering, metallurge, etc. in recent years. Its principle has been very widely utilized in many technological processes. However, in contrast to this situation, theoretical study on dynamics of chemical transport is not quite so sufficient.The present paper deals with dynamical process of chemical transport. A theoretical analysis carried out, a mathematical model is constructed, and the governing equation is solved by using the method of Laplace transformation. Thus, with the results of this paper, it is not difficult to calculate the transport rate of the source material and the free deposition rate of the solid production on the wall of the tube; to determine the position of starting deposition L* and the concentration distributions of gaseous species in the tube.

A chemicophysical and fluid dynamic model is formulated for the mumerical simulation of the process in a titanium dioxide reactor by the method of chloridizing and oxidizing. Turbulence, species diffusion, chemical reaction, two phase flow are considered in the model. The governing equations are solved by using the algorithm of SIMPLED which was devised by partankar and spalding. The flow temperature and concentration fields are obtained which give us a clear picture chemicophysical and fluid dynamic process in the reactor. We preformed a careful investigation on the effect of wall heat transfer and chemical reaction on the flow. The result of the paper can be used as a theoretical guide by the engineers in their design of such reactors.
