| Abstract: | 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. |
