Prof. Stuart Dalziel


  • 2016-present Professor of Fluid Mechanics, Department of Applied Mathematics and Theoretical Physics
  • 2012-2016 Reader in Fluid Mechanics, Department of Applied Mathematics and Theoretical Physics
  • 2001-2012 University Senior Lecturer, Department of Applied Mathematics and Theoretical Physics
  • 1997-present Director of the GK Batchelor Laboratory


Stuart is in charge of DAMTP's GK Batchelor Laboratory, in which physical experiments are undertaken to complement the Department's theoretical interests. A central focus of Stuart's work is therefore experimental, although he is also heavily involved in both numerical and theoretical studies.

Within the Laboratory, Stuart is motivated by the fluid dynamics of the environment in which we live, and how this affected by the earth's rotation and density variations, whether stabilising or destabilising. He is also concerned about industrial problems, including making chemical processes greener and cleaning up our environment.

Recent projects have included

  • Internal gravity waves 
  • Rayleigh-Taylor and Richtmyer-Meshkov instabilities
  • Buoyant plumes
  • Rotating turbulence
  • Stratified turbulence
  • Resuspension
  • Granular flows
  • Decontamination
  • Reactive flows

Stuart also has significant interests in image processing as a technique for extracting high-resolution quantitative information from fluid flows and is author of DigiFlow, a system designed for this purpose.
