Large Eddy simulation of particle laden jet flow with aerodynamic three way coupling

Jadoon, Asim LU and Revstedt, Johan LU (2010)
Abstract
A model to incorporate for aerodynamic 3-way (indirect) coupling between mono dispersed particles is proposed.

The model is applied on particle laden jet flow and the results are compared with 2-way coupling.

The particle drag coefficients are corrected based on the relative position of the particles. The correction factor

is obtained from the pre-computed lookup tables. The particles are tracked by Lagrangian particle tracking (LPT),

whereas the continuous phase is modelled by Large eddy simulation (LES).

Particle mean axial velocity is found to be large in 3-way coupling which results in more particle penetration in the streamwise direction due to less momentum transfer of the particles to... (More)
A model to incorporate for aerodynamic 3-way (indirect) coupling between mono dispersed particles is proposed.

whereas the continuous phase is modelled by Large eddy simulation (LES).

Particle mean axial velocity is found to be large in 3-way coupling which results in more particle penetration in the streamwise direction due to less momentum transfer of the particles to the fluid phase. The fluid velocity is also observed to be higher in case of 3-way coupling due to high mass loading which results in reduced axial fluid velocity fluctuations. The void faction is also found to be higher

in 3-way coupling due to particle entraiment and less interaction with turbulence (Less)
