The objective of the present work is to study the effect of different model lift coefficients on the particle trajectory in dilute two-phase gas-solid horizontal channel flow. Five different model lift coefficients are selected from the open literature. A hybrid Eulerian-Lagrangian method is employed to study the dilute two-phase gas-solid flow in horizontal channel. Reynolds averaged Navier-Stokes equations with k-e closure are used to model the fluid (carrier) phase. Particulate phase is treated via Lagrangian approach. Particle-wall collision is handled by using the impulse-momentum equations. Effect of particle lift both due to shear and rotation are considered. Present computed results of the particle trajectories with simplified assumptions agree closely with the simulated results of (1) other authors using two-way coupling, and (2) FLUENT~R (Version 6.1) with one-way and two-way coupling. Particle rotational velocities as high as 1800 revolutions per second are encountered due to particle-wall collision. Particle trajectories are found to be significantly affected by lift force due to particle rotation; whereas effect of lift due to shear is found quite small.
