RANS Modeling in Gas-Solid Particle Vertical Flow (Keynote)

Results from the mathematical modeling of gas-solid particle flow in an upward pipe flow performed in the framework of RANS are presented. The aim of the study is to implement an original model of closure for the transport equations of dispersed phase along with particles involvement into the turbulence motion into further developed the modeling description using the RANS approach. It allows the retention of the diffusive terms in both streamwise and radial directions. The numerical simulations show that the RANS method captures the main characteristics and overall behavior of the particle and gas-phase motion in the pipe.
