Heat conduction and mass diffusion
1998In this chapter we will deal with steady-state and transient (or non steady-state) heat conduction in quiescent media, which occurs mostly in solid bodies. In the first section the basic differential equations for the temperature field will be derived, by combining the law of energy conservation with Fourier’s law.

Mass flow, numerical dispersion and diffusion
1993If water containing dissolved salts (e.g. fertilizer) infiltrates into the soil, a gradual increase in salt concentration will be observed at a certain depth. The curve of the change in salt concentration against time at a certain depth is called the breakthrough curve. The rounded shape of this curve can partly be explained by diffusion of the salt in

Analysis of nonlinear mass and energy diffusion
Physical Review A, 1985Before a complete analysis can be made of the radial transport of mass and energy in the presence of magnetic fields, the nonlinear diffusion of mass and energy across magnetic fields must be well understood. ' In pursuit of this goal, this paper is concerned with a mathematical analysis of a simple model of slow diffusive selfrelaxation of a ...

Mass diffusivity of food products
Food Reviews International, 1999Abstract Moisture diffusivity (Dm) and drying constants (k) of food products, raw and processed, are reviewed. These mass transfer properties were classified into various commodity groups such as fruits and vegetables, cereal products, meat products, gels, etc. These properties were also reviewed for the foods during frying process.

Osmosis: Diffusion or Mass Flow?
BioScience, 1968water resulting from hydrostatic pressure differences within the submicroscopic pores of a membrane. I wish to point out here that Stein's view applies only to porous membranes and that osmosis in biological systems does not necessarily involve a mass flow of water through pores. Whether osmosis occurs by bulk flow or by simple diffusion depends on (1)
