Aims: To introduce students to the principles and practices involved in selected areas of transport phenomena, to advance students' understanding of the principles of complex single phase flow, and to introduce students to the principles and applications of multiphase flows.
Learning Outcomes: After successively completing this unit the student should be able to describe a wide variety of non-Newtonian behaviour and carry out basic calculations; be able to carry out simple calculations with the Navier-Stokes equations; and have an appreciation of the theory of turbulent flow. On successful completion of this unit the student will also have acquired an appreciation of the complexities of two-phase gas-liquid flow; an understanding of oil production techniques; and gained an introduction to the use of Computational Fluid Dynamic (CFD) codes. Skills: How to apply some of the basic fundamental knowledge gained in this unit and earlier parts of the chemical engineering course, to model a real system. These skills are taught, mini-problems are set in the class, tasks are set, and finally students are assessed. Content: Non-Newtonian fluids including Bingham fluids; Derivation and application of the Navier-Stokes Equations; Steady-state and unsteady-state diffusion; Turbulent flow models; Two-phase gas-liquid flow in channels: theory and applications. For example: two-phase flow patterns; void fractions; determination of pressure drop; Taylor flow; Lockhart-Martinelli correlation; and industrial applications. Oil production covering the basics of primary, secondary and tertiary recovery processes. An introduction to the challenges of using commercial CFD codes to model real systems. |
