A numerical study based on the κ-ε two-equation turbulent model, was conducted to broaden our knowledge of the flow features in a U-beam tube bundle. U-beam tube bundle could be arranged stagger to play a role of inertial gas-solid separator in Circulating Fluidized-Bed Boiler system. This paper presented the velocity, velocity streamlines, pressure loss, turbulent kinematics energy, turbulent intensity of the fully developed flow field, and analyzed the distributions and variations rule. The paper also transferred the parameters to dimensionless group, discussed the changing law and magnitude of the dimensionless physical quantities when inlet velocity changed. Figs 8 and refs 10.
