Multiphase platforms dominate approximately each sector of technology and know-how, and the strategy of quantity averaging offers a rigorous origin for the research of those structures. the advance relies on classical continuum physics, and it offers either the spatially smoothed equations and a style of predicting the powerful shipping coefficients that seem in these equations. The textual content relies on a ten-week graduate path that has been taught for greater than twenty years on the college of California at Davis and at different universities worldwide. difficulties facing either the theoretical foundations and the purposes are incorporated with every one bankruptcy, and distinct recommendations for all difficulties can be found from the writer. The path has attracted individuals from chemical engineering, mechanical engineering, civil engineering, hydrologic technological know-how, arithmetic, chemistry and physics.

E y and it dominates the manner in which CAy is distributed in the y-phase. 4-28) and the volume diffusive source in Eq. 4-22 can be discarded. Further simplification of the closure problem can be achieved if we can demonstrate that CAy is small compared to (CAy) y. Directing our attention to the boundary condition given by Eq. 4-31) originally given by Ryan et al. (1981). 4-34) For practical reactor design problems, the particle Thiele modulus is usually less than ten (<1>2 ~ 100) while fy is typically many orders of magnitude smaller than L, thus Eq.

13 and the results are used in Eq. 4-62 to determine the effective diffusivity tensor. 13 would provide essentially the same result as the Chapter 1 48 theoretical model shown in that figure. 13. 5 ANISOTROPIC SYSTEMS While many systems that are isotropic with respect to diffusion are available in the laboratory, most natural systems and many processed materials are anisotropic. The process of extrusion may be the cause of anisotropy in catalyst pellets (Satterfield, 1970, Sec. 2), and the experimental results of Currie (1960) for kaolin suggest that any kaolin-based catalyst will exhibit anisotropic behavior.

6-7, the justification ofEq. 6-10 is an important matter. 2 ISOTROPIC SYSTEMS It is worthwhile to note that there are no homogeneous, isotropic porous media. By isotropic one means invariant to any coordinate rotation and by homogeneous one means invariant to any coordinate translation, and a little thought will indicate that there are no porous media that could satisfy these geometrical requirements. On the other hand, there exist porous media for which the diffusion process is isotropic and for which the effective diffusivity tensor and the porosity can be treated as constants.
