Determination of the Most Likely Wear Zones of Pipe Bends in the Pulsed Pneumatic Conveyor at the RT-1 Plant

Resumo

The results of an experimental investigation and numerical modeling of the most likely high-wear zones in 90° pipeline bends in the pulsed pneumatic conveyor system at the RT-1 plant of the Mayak Industrial Association are presented. The experimental studies were conducted on a model of a pulsed pneumatic conveyor system; the numerical modeling of the gas-dynamic flow in the pipeline channel was performed in a model of a two-dimensional non-stationary motion of a compressible medium. It was found on the basis of the experimental results obtained using the model and numerical modeling in the homogeneous approximation that local regions with high wear of walls in the 90° pipe bends in the pulsed pneumatic conveyor do indeed exist and their experimentally found positions agree with the calculations.
