EG-100 Chemical Process Principles

The module provides basic intellectual tools for analysis and design of chemical (and biochemical) processes. The module will cover flows of material and energy to and from a variety of processes and production of complete mass and energy budgets and estimates of process efficiency. Some hazards related to release and exposure to flammable materials in relation to their properties (especially vapour pressure) will be covered. Only a basic level of chemical knowledge is required and the module is suitable for Process Engineering students.
EG-M01 Complex Fluids and Flows

This module considers the rheology of complex fluids. Course content provides an introduction to rheology from basic classifications of non-Newtonian materials to how the material properties affect processing operations. Consideration is given to the influence of product rheology and the manufacturing process, quality control and how this influences performance and end-user perception. Rheological methods for the characterisation of non-Newtonian materials are reviewed and means by which the results of such tests can be used to describe and predict advanced aspects of transport processes involving non-Newtonian fluids are considered. Materials of interest range from simple inelastic time-independent fluids to more complex viscoelastic systems. Measurement techniques considered range from simple shear viscometers to advanced rheometrical techniques for the characterisation of evolving systems (those which are changing with time due to chemical or physical transformation).
