Large Eddy Simulation of Gas - Second Order Moment of Particle Approach for Riser

Article Preview

Abstract:

Flow behavior of gas and particles is performed by means of gas–solid two-fluid model with the large eddy simulation for gas and the second order moment for particles in the riser. This study shows that the computed solids volume fractions of two cases are compared with the experimental data using a two-dimensional model. The gas and solid velocity is computed.
