An introduction to heat-transfer and mass-transfer operations, further topics in chemical and process thermodynamics.
Course ContentThis course is in three sections: a 14 lecture block on Heat Transfer is taught by Professor Shusheng Pang, Dr. Justin Nijdam teaches a 10 lecture block on Mass Transfer and Dr Aaron Marshall has 12 lectures building on the Thermodynamics from ENCH291. Students should gain the following:Heat Transfera) Sufficient understanding of the principles of heat transfer to: Use the electrical analogy to interpret systems involving conduction and convection; Analyse one and two-dimensional steady state conduction problems; Select and apply appropriate correlations for convection heat transfer; Be prepared for the detailed analysis of heat exchangers in the second professional year.Mass Transferb) Appreciation of the role of diffusional processes in the separation of mixtures to include: Brief outline of important chemical engineering separation techniques including distillation, absorption, extraction, leaching, drying, membranes; Outline of Fick’s law for steady state molecular diffusion, diffusivity; The differences between molecular & eddy diffusion; Introduction to the theory of interfacial mass transfer; The definition and use of mass transfer coefficients; Be prepared for more detailed analysis of gas/liquid and liquid/liquid operations in the second professional year.Thermodynamicsc) An understanding of the 2nd Law and its applications, including: Identification of the 1st Law limitations; Development of the second law based on the heat engine; The entropy balance based on real-world observations; Liquid-Vapour cycles, heat engines, heat pumps / refrigeration technology; Maximum efficiency and lost work; Statistical thermodynamics and entropy; Be prepared for advanced thermodynamics in second professional year.Relation to Other CoursesThis paper provides essential background for ENCH393 (Fluid Mechanics and Heat Transfer), ENCH396 (Chemical Engineering Separations 1) and ENCH392 (Thermodynamics and Chemical Reaction Engineering).
