    The model is limited to the one-dimensional problem of an infinite slab. In principle, one could simply take the model equations, discretize them, and solve them by a method suitable for non-linear problems, e. In their works, the thermophysical properties of the drying material are taken as constant, and the effect of heat transfer on the moisture loss is neglected. Patankar The works dealt with drying processes at different air temperatures and flow velocities.

The topics covered in this textbook are comprehensive, and the treatment is extremely thorough; thus The readers who are potentially interested include practitioners, modelers, managers and researchers as well as students at the graduate and upper undergraduate level in civil and environmental engineering. Suzuki and Maeda then solved the nonlinear diffusion problem by using dimensionless variables for the diffusion coefficient, moisture content, time, and space. Broadly speaking, the first class of methods is suitable for relatively slow transients, such as fluidized beds, or phenomena with a long duration, such as flow in pipelines.

    This is a common function used to describe the effective diffusion coefficient. The review of drying models as such serves as the basis for the development of a framework for numerical simulation. Course Contents number of lectures in brackets : I.

By using the capillary theory to describe the drying of granular materials such as coarse, medium, and fine sand and based on the collected experimental data, Ceaglske and Hougen [ 14 ] suggested that the effective diffusion coefficient should be considered as varying during drying and proposed the following diffusion model: The effective diffusion coefficient is now considered as a function of moisture content, Introduction to modeling of transport phenomena in porous media book, material type, and drying history.

Model use 1. Afterwards, they describe the single and multi phase flows in simplistic and complex porous structures in terms of macroscopic and microscopic equations as well as of their analytical and numerical solutions.

More recently, Guillard et al. The paper reviews the continuum approach to modelling the transport of mass, momentum and energy, of phases and of their components in a porous medium domain. The diffusion model can lead to an incorrect prediction and misinterpretation of the moisture distribution or of the drying behavior due to the fact that only moisture transport is considered and that the physical meaning of the diffusion coefficient is either lost in the case of a constant or it becomes a lumped parameter of all simultaneous effects in the case of a variable.

About this book Introduction The main purpose of this book is to provide the theoretical background to engineers and scientists engaged in modeling transport phenomena in porous media, in connection with various engineering projects, and to serve as a text for senior and graduate courses on transport phenomena in porous media.

The previous chapter, with its direct simulation of the fluid flow and a modeling approach to the particle phase, may be seen as a transition between the methods for a fully resolved simulation described in the first part of this book and those for a coarse grained description based on the averaging approach described in chapter??.

Often the porous material contains several fluid phases, and the various extensive quantities are transported simultaneously throughout the multiphase system. The Method of Volume Averaging, S. Effective medium approximation: Equivalent thermal conductivity, viscosity, dispersion. In all these disciplines, management decisions related to a system's development and its operation have to be made.

However, in this region, the movement of adsorbed water may also play an important role [ 38 ]. Koptyug et al.

Table of Contents. In solving the diffusion equation, this parameter is usually taken as constant or in the form of linear, exponential, or polynomial functions of moisture content.

However, this model is still used as a simple way to describe drying in some cases. Over the years, many works were undertaken to understand the mass and heat transport phenomena during drying.

Sherwood showed that the moisture transport involves two independent processes: the evaporation of moisture at the solid surface and the internal diffusion of liquid to the surface. The approach is based on the analytical solution of the diffusion equation for one-dimensional isotropic diffusion with a flux-type boundary condition in the form of mass flux.Introduction to Modeling of Transport Phenomena in Porous Media - Ebook written by Jacob Bear, Y.
