Most of John Elliott's life is centred about the University of Hull.

His research interest lies in the general area of fluid mechanics. Although this covers a very wide range of research activity, his main expertise lies in high Reynolds number viscous flows.

Dr Elliott's initial interest was with regard the phenomena of boundary layer separation, both for steady-state and unsteady flows.

He is also interested in fluid problems involving heat and mass transfer. This emanates from his PhD thesis (under Eric Watson) an investigation into the melting of ice-shapes.

Research

Research Interests

  • High Reynolds number viscous flows

  • Boundary layer separation

  • Fluid problems involving heat and mass transfer

Research groups

Research Group: Applied Mathematics

  • Collaborated with Prof F T Smith (UCL), Dr A Bassom (Exeter), and a research student (M Strange) on boundary layer studies. This work led to a research consultancy with BAE (Brough), to establish a set of numerical codes to solve the compressible Reynolds-averaged Navier-Stokes equations.

  • Collaborated with Prof G Poots (Hull) on fluid problems involving heat and mass transfer, with particular regard to freezing, and with a research student (P Flood) on the effect of icing on cables with separated flow.

  • Collaborated with Prof. A Cummings, in the Department of Engineering, in the study of acoustic waves, with a EPSRC-funded research studentship (S. Witty) investigation of tones heard in corrugated pipes.

  • Collaborated with Prof. V. Kopiev on research into jet noise from corrugated nozzles. This work was continued with a research student (S. Thomas). He has also helped with supervision student (M. Burton) into the study of Bernard convection in liquid-crystals.

  • Recently worked with Prof F T Smith to consider the effect of supercooled water droplets impacting with both rigid walls and thin water layers, with particular regard to the icing of helicopter rotors.
