Abstract

In the present work numerical simulation of fly ash air mixture through a horizontal pipe of 69mm diameter and 2000mm length, has been done using @ANSYS 14.0. Volume fraction of fly ash 0.11 by weight, particle size 30µm and density of fly ash 2300kg/m3 has been taken. The understanding of the underlying flow, physics of such a complex multiphase system is of utmost importance in order to design the engineering equipment handling the flow. The complexity in these flows can be best analyzed through computer simulations with less time and high accuracy. The above facts pave the motivation of the present study on the erosion prediction of the complex two-phase flow in pipelines. In the present investigation, systematic studies have been carried out to evaluate the effect of different mass flow rates on the rheological and flow behaviour of solid gas suspension. Present study has made an attempt to explore that untouched area of research. Based on the empirical correlations developed in the past literature for pressure gradient and erosion mass loss in the flow, the validation has also been done with the experimental results available in the past literature.
