CFD Validation for Forces on Immersed Tubes in Fluidized Bed

Sushil Kumar

Fluidized bed is widely used in chemical processing industries and heat transfer operations because of high heat transfer and mass transfer rates due to intermixing. This work deals with estimation of the force imparted by the bed material on the tube assemblies in a fluidized bed by CFD technique. The gas-solid flow was simulated by means of a multi-fluid Eulerian model incorporating the kinetic theory for solid particles. The pulsating forces were compared to experimental data of Kennedy et al. A good approximation was observed in force exerted over different tubes. However minor differences were observed in interval duration of the peak forces.
