Why study Computational Fluid Dynamics?

1
Why study Computational Fluid Dynamics?

• Associate Professor David Fletcher
• Department of Chemical Engineering

2
What does it involve?

• Computer modelling of a wide range of flow, heat
  transfer, reaction and environmental problems.
• Can either do a PhD entirely based on computation
  (but you will need good mathematics) or use it as
  part of a PhD with other staff members where it
  will form a chapter or two.
• Training in ANSYS CFX, a leading commercial
  software package.

Mixing Studies at Toulouse
4
Cotutelle Programme

• Part of the time in France, part here.
• Two degrees.
• Must pass entrance exam in French.
• Joelle now lives in France.

Spray dryer modelling

• Joint work with Tim Langrish.
• Experimental and computational components.
• We are world leaders in the simulation of flow
  and drying processes in spray dryers.

7
Flow in micro-systems

• Joint work with Brian Haynes and Cathy Xuereb
  (Toulouse).
• Massive growth area worldwide.
• Aim is to develop bench scale chemical plants and
  chip scale diagnostic facilities.
• Already have world-leading facilities and
  research programme.

Effect of Re on secondary flow around pipe bends
10
Pharmacological flows

• Joint work with Kim Chan (Pharmacy) and others.
• Studying ways to improve drug delivery to the
  lungs.
• CFD is used to determine the flowfield and
  particle behaviour.

Wrap-up

• Lots of projects across the Department as Tim
  Langrish, Brian Haynes, Jose Romagnoli, Jim
  Petrie and Geoff Barton all use CFD.
• Good skills to have for employment or research.
