Exclusions
Description	This module covers the critical theoretical material for mass and heat transfer. It extends the introductory material taught in Introduction to Transport Phenomena and Thermodynamics. This includes a general energy balance for conduction and common simplifications for symmetrical 2-D and 1D problems. The lumped capacitance method is discussed, as well as heat transfer from extended surfaces. Engineering processes such as membrane separations and adsorption are described. In addition, the critical theoretical material for momentum transport is discussed and addresses viscous and turbulent flows between solid boundaries is included. The principle of similitude is applied to the design and analysis of pumped flow systems and cost optimisation is applied to the design of pipelines. Engineering applications such as complex pipe networks and combined pipe-pump systems are analysed. The heat transfer material covered is further extended to cover internal/external convection and radiation. Computer based methods of solution of heat and mass transfer problems are introduced and applied to some process examples. Typical content would include: • Use of lumped capacitance method to calculate temperature distributions and heat flux in transient cooling/heating problems; • Simplified general energy balance to describe specific problems (2D or 1D simplifications) and definition of appropriate initial/boundary conditions; • Calculation of heat flux from finned surfaces; • Description of how diffusion influences the operation of absorption, adsorption and membrane systems; • Description of the two film model and application of this concept in selected mass transfer problems; • An analysis of the flow of real fluids between solid boundaries; • Application of the arguments for friction and energy conservation to calculate pumping requirements for complex pipe systems, selection of appropriate pump types, and design pipelines economically; • An analysis of the flow over a flat plate and around cylinder/sphere, compare hydrodynamic and thermal boundary, and physical interpretation of Nusselt, Reynolds and Prandtl numbers; • Calculation of heat transfer rate by radiation, understanding of the concepts of black/grey bodies and radiation of gases; • Description of the qualitative heat transfer during boiling/condensation; • Completion of the appropriate momentum and heat balances and calculation of transfer coefficients based on measured experimental data.
Learning Outcomes	By the end of the module the student should be able to: Use fundamental transport phenomena (underpinning engineering science) understanding to generate and simplify relevant engineering problems. Use fundamental understanding of transport phenomena mathematics to solve relevant engineering problems.
