Dr. John Shrimpton teaches fluid mechanics in university of Southampton. His main research activities are physics of dense particle systems (i.e. agglomerates and unstable heaps of particles, usually applied to pharmaceutical powder systems), particle-turbulence interactions (clouds, most industrial spray systems) and multiphase systems that contain electric charge (plasma reactors, electrostatic sprays). He uses both experimental methods and optical diagnostics in addition to actively developing several high quality numerical codes for the computational simulation of particle laden flows.
