Determination of time duration of polymer particle collision in fluidized bed using discrete element method
Original language description
Discrete element method (DEM) is used for the investigation of the collision behavior of particles in polymerization reactor. Colliding particles in the DEM representation consist of individual mutually force interacting discrete elements, the trajectoryof each of them is given by the second Newton's law of movement. The collision time was evaluated as the time period when there exists at least one force connection between discrete elements from different colliding particles. The agglomeration of polymer particles is caused by various adhesion forces (e.g. liquid-bridge force and the force reflecting entanglement of polymer chains) acting at a characteristic time scale. Characteristic time of the liquid bridge formation and of the chain entanglement was compared to the collision time obtained by simulations of collisions of polymer particles with the aim to evaluate whether this collision time is long enough for the formation of particle agglomerate.
