Symposium B-4: Turbulent Transport in Multiphase Flow

Symposium Technical Description

The role of turbulence in the transport of multiphase mixtures is ubiquitous across a wide range of industrial and environmental flows, ranging from spray combustion to fluidized beds to sediment transport in oceans and rivers. The challenge of a mobile interface separating the phases at the small scale, combined with the well know challenge of a turbulent carrier fluid, presents a multitude of closure challenges for practical modeling of these systems. This symposium aims to focus on presentations of experimental, computational or theoretical advances in understanding and modeling the coupling behavior across the spectrum of dispersed multiphase systems.
