MONTE CARLO SIMULATION OF HORIZONTAL PNEUMATIC CONVEYING BASED ON THE ROUGH WALL MODEL

Abstract

On the basis of wall roughness, a simple model is presented to explain the irregular bouncing phenomena of particles in pneumatic conveying. By introducing a random factor to the model, a pneumatic transport process was simulated by Monte Carlo method.
The model could fairly well account for the concentration and velocity distribution and the rate of revolution of particles. Even very small degree of roughness was found to have a great influence upon the behaviour of particles.
