Eulerian Modeling of Gas-Solid Flow with Solid Volume Fraction up to 0.1

ABSTRAKT

This paper presents the results related to the CFD simulations using the two-fluid model approach to study the effects of solids volume fraction and gas phase Reynolds number on the pressure drop in a fully developed gas-solid flow. A horizontal pipe of internal diameter 30 mm and length 3 m is considered for this study. The Gidaspow drag model with algebraic granular temperature model is used for the simulations. Numerical results are compared with the bench mark experimental data, and good agreement is found with a maximum deviation of −20 %. The solids volume fractions ranging from 0.01 to 0.1 and gas phase Reynolds numbers ranging from 20000 to 100000 are used in the present study. The numerical results indicate that the magnitude of the pressure drop is higher for higher values of the solids volume fraction and gas phase Reynolds number.
