  • EG-211 Fluid Flow

    This module aims to extend the previous Fluid Mechanics (EG-160) module, to introduce the flow of fluids around particles, through porous media, pipes and devices (with special reference to the design and operation of differential head flowmeters) to provide a balance between theory and practical aspects of equipment used in chemical engineering, such as mixing impellers (with special reference to the Rushton-turbine type mixer) and packed beds (spherical particles). The module also addresses elements of non-Newtonian fluid flow in terms of the Power-Law Model and the Bingham-Plastic Model (for yield stress materials) and considers the flow of these materials in pipes.

  • EGA326 Chemical Engineering Design Project

    This module aims to give students experience in handling a complex and integrated engineering process design. This task will require, and so reinforce, the material taught throughout the undergraduate course and an additional amount of material from directed private study. The module provides transferable skills related to working in a team environment on a major project.

  • EGNM02 Soft Nanotechnology

    This module introduces fundamental concepts in soft condensed matter physics/chemistry, and looks at the use of this knowledge in a wide range of 'soft matter'-based applications, including organic electronics, micro/nano-fluidics and molecular motors. A strong emphasis of the course is the fundamental physical processes that control the structure/behaviour of macromolecules.
