411-331 Heat and Mass Transport Processes 1.

Students successfully completing this subject will be able to apply the principles of heat transfer to conduction and radiation heat transfer problems and to analyse and design separation operations including adsorption and ion exchange, multicomponent distillation, simultaneous mass and heat transfer, membrane separation processes and mass transfer with chemical reaction.

Content: Heat transport processes radiation: basic principles of radiation; shape factors (viewfactors); radiation between grey surfaces in the network approach; applications of networks for various situations. Conduction: Fourier's Law of heat conduction; multi-dimensional heat transfer equations; steady-state heat conduction and the Laplace equation; steady-state conduction with distributed heat source and the Poisson equation; simplified equation for steady-state heat conduction; fins; transient heat conduction and the diffusion equation; examples of simple solution of transient heat conduction; brief introduction to numerical methods for heat conduction problems. Mass transport processes: Multicomponent distillation, including short cut and rigorous techniques for the prediction of column performance. Solvent extraction, including the effect of axial dispersion. Adsorption and ion exchange - types of absorbents, fixed bed adsorber models, isothermal equilibrium and non-equilibrium design and operation. Mass transfer with chemical reaction, homogeneous and heterogeneous reactions, and application to equipment performance and design.
