Course content
The is given in the AUTUMN 2010.
Fick´s, Navier-Stokes, Euler´s, Bernoulli's and Newton's second equations and conservation laws in transport processes. The Chapman-Enskogs, two-film, Eyrings, hydrodynamical, penetration, and varying interface renewal theories. The models and concepts of Dufour, Soret, Onsager, Kingery, Luikov and Stamm. The analogy of micro and macro transport processes. Criteria of similarity, model and object equations. Equations for steady state and transient convective and molecular diffusion in gases, liquids (ionic or not), concentrated solutions and porous solids. The gradients of concentration, moisture, temperature, pressure and phase change. Dimensionless groups and experiments on internal and external transport in laminar and turbulent flows. Transport properties in multicomponent mixtures. Transport in bubbles, droplets, cellular, capillary and porous solids.
Quasi-steady method and mass transport in equally-accessible surfaces. The development of transport rates in with chemical reaction, diffusion and convection. Sorption isotherms and spacial polytherms equations with effect of temperature. Sorption inflection points and distribution of micro and macropores and related equations. Experimental application of transport equations and correlations.
