Use of Lagrangian methods to describe particle distribution in horizontal turbulent flows
Abstract
Lagrangian methods are used to examine the distribution of particles in a two-dimensional turbulent horizontal flow. The concentration field is viewed as resulting from a distribution of line sources of particles. The influence of gravity on the behavior of the particles from one of these sources is assumed, on average, to act independently from the turbulence. Two cases are considered: gas-liquid annular flow in a two-dimensional channel and sediment transport.
