Transport Phenomena

Governing equations for momentary mass and heat transport. Laminar and turbulent flow, laminar and turbulent boundary layer. Brief introduction to rheology and non-Newtonian fluids for biological systems. Steady and un-steady diffusion in dilute and concentrated fluids in different geometries. The Fick and Stefan-Maxwell equations, multicomponent diffusion. Diffusion in porous media. Generalised equations for momentum, mass and heat flow. Laminar and turbulent boundary layers. Mass transfer models. Simultaneous heat and mass transfer and transfer analogies. Introduction to Matlab (Solving ordinary differential and partial differential equations, discretization).

KNOWLEDGE - Understand the mechanisms for combined transport of mass, energy and momentum - Analogies between the transport processes - Steady state and transient diffusion in various geometries - The Maxwell-Stefan concept for multicomponent diffusion SKILLS - Calculate hydraulic parameters in absorbers - Calculate mass and heat transfer in absorption and stripping. - Calculate size of absorber and stripper(Packing) - Develop the set of equations for kinetic and equilibrium models GENERAL COMPETENCY - General understanding of mass and heat transfer processes in contactors where chemical reaction takes place

Lectures with worked-through examples. The exercises partially use Matlab. Expected workload per week is three hours with lectures, two hours with exercises, and seven hours of independent studying. The total workload in the subject is 200 hours distributed on lectures (40%) and projects/independent studying (60%).
