An efficient lagrangian trajectory model for predicitng complex turbulent two-phase flows using the curvilinear coordinates

X. Chen ; J. Pereira | 1997

In this article, a numerical procedure is developed to extend the SPEED (Stochastic-Probabilistic Efficiency Enhanced Dispersion) model to the non-orthogonal curvilinear coordinates for the efficient prediction of dispersed turbulent two-phase f[...]

Computation of dispersed turbulent liquid-particle flows impinging a centerbody using an improved langrangian stochastic model

X. Chen ; J. Pereira | 1997

A computational study is carried out for a dilute turbulent liquid-particle flow impinging a centerbody through a sudden-expansion pipe. An improved Lagrangian stochastic particle-dispersion model and a second-moment Reynolds-stress transport mo[...]

Computation of turbulent evaporating sprays with well-specified measurements : a sensitivity study on droplet properties

X. Chen ; J. Pereira | 1996

An extensive numerical study was carried out for a confined evaporating spray in a turbulent, heated gas flow using a published well-defined experimental dataset. The Eulerian-Lagrangian stochastic models were employed for spray calculations whe[...]
