Transfer Operations and Thermodynamics

Description

This course is in three sections: a 14 lecture block on Heat Transfer is taught by Professor Shusheng Pang. Prof Phil Wankat, 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 Transfer
a) 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 Transfer
b) 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.

Thermodynamics
c) 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.
