Numerical prediction of pressure drop for pneumatic conveying of air-fly ash mixture through pipeline.

Abstract

Abstract Many researchers are working in the field of pneumatic slurry transportation, where the rheological parameters involved in the flow. In the present work is a numerical simulation for the study of pressure drop of 30µm particle size of fly ash air mixture flow through a circular pipe was investigated through ANSYS Fluent. The present paper introduces a simplified 3-D Eulerian model along with RNG k-ε turbulent model. It was observed that the pressure drop was maximum for minimum mass flow rate of air and as the mass flow rate increases the pressure drop decreases and it becomes constant at a threshold mass flow rate for this particle size, which qualitatively matches with the experimental results observed by Bansal et al. (2013).
