Description: Fluidization and settling of a bed of monosized solid particles have been simulated using Discrete Element Method. The simulation approach has been based on the fact that particles in a fluidised state undergo random motion. Therefore, using a one way-coupling we have developed a model in which the fluid velocity has been simulated by using a mean and a fluctuating term and the momentum transfer has been achieved through the use of the drag force. The effect of the fluctuating fluid velocity on the settling of 8 mm particles has been investigated. Moreover, a model validation for the particle velocities has been performed against the available experimental data which revealed a good agreement.
