Development of a parallel multiphase Lattice-Boltzmann solver to study Stokes number effects on particle trajectories

Particle-laden flows are important owing to their relevance to many engineering devices such as coal combustors, gasifiers and solar thermochemical reactors. In a recent experimental study by Lau and Nathan [1], it was found that particles in a turbulent pipe flow tend to migrate preferentially depending on their Stokes number (St). Particles with a high St (\u3e10) are concentrated near the axis while those with low St
