Description

This is a key course in chemical engineering covering fluid mechanics and industrial applications, particle technology and heat transfer. These topics provide the knowledge and tools which enable the design and analysis of many chemical engineering processes.

The following topics are taught in this course:

Heat Transfer (6 lectures):
o Thermal radiation heat transfer.
o Heat transfer from finned surfaces.
o Unsteady heat conduction.

Momentum Conservation (9 lectures):
o Microscopic mass and momentum balances; the Navier-Stokes equations.
o Simple applications of microscopic balances; fluid statics and unidirectional flow.
o Flow at small Reynolds number (creeping flow).
o Flow changes at increasing Reynolds number; inviscid flow.
o Boundary-layer theory and drag.
o Computational fluid dynamics (CFD).


Non-Newtonian Fluids and Flows (4 lectures):
o Qualitative features and types of non-Newtonian fluids.
o Flow profiles and friction factors for non-Newtonian flow in tubes.
o Measurement of viscosity and non-Newtonian properties.

Filtration (3 lectures)
o Types of industrial filters and basic operating principles.
o Cake filtration.
o Depth filtration.


Gas-liquid two phase flow (4 lectures)

Mixing and agitation (2 lectures)

Particles and fluidisation (8 lectures):
o Particle size distribution and measurements.
o Single-particle fluid mechanics.
o Fluidisation.
o Cyclone.

Learning Outcomes

  • Sound understanding of fundamentals of fluid mechanics and heat transfer.
  • Application of fluid mechanics fundamentals to complex flows including Non-Newtonian fluids, two-phase flow, filtration and mixing/agitation.
  • Understanding of fundamentals of particle fluidisation and challenges of particle processing.
  • Applying technics for particle characterisation.
  • Understanding of thermal radiation heat transfer and applications.
  • Evaluating heat transfer problems to determine significant heat transfer resistances and simplifications of the problems.
  • Applying numerical methods to complex heat transfer problems.
