چکیده
|
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solid boundary layer flow using a fully eulerian two-fluid model. the closures required for equations describing the particulate phase are derived from the kinetic theory of granular flows. gas phase turbulence is modeled by one-equation model and solid phase turbulence by mlh theory. results of one-way and two-way coupled approaches are compared with the available experimental and numerical results. results show that one-way coupled approach is more efficient for particulate velocity prediction in dilute flows. but, if the gas-phase flow characteristics are desired, the twoway coupled approach should be used. effects of free stream velocity on the coupling are discussed.
