Structures in Chaos: Representative Gas-Turbine Combustor Port Flow —Vishal Saini, Loughborough University

Instantaneous turbulent flow state in a representative gas-turbine port flow. Six radial port-jets issued from outer annulus impinge onto each other in a bulk cross flow. The port Reynolds number is 22,600. Key features: highly-vortical unsteady flow, horse-shoe port vortices, central-recirculation zone, fifth-order accurate LES using Nektar++.
