Computational fluid dynamics analysis on role of particulate shape and size in erosion of pipe bends
https://orcid.org/http://orcid.org/0000-0002-1668-8765
This study is performed to investigate the erosive degradation of pipe bends by the action of slurry particles. The purpose of this research is to better elaborate how the particulate properties namely shape and size, which affect the erosive degradation. Numerical computation is done using an ANSYS R.21 FLUENT package. The Euler–Lagrange model was adopted in conjunction with standard k–ε model in order to provide an accurate prediction of erosive rate. For this research, the geometry of 50 mm diameter and 1.5 m long pipeline was designed in Creo software package. The radius (bend)-to-diameter (pipe) ratio (r/D) was taken constant as 1.5. During the numerical simulations, the velocity was taken as 5 m/s. It was found that the erosion of pipe bend increases with decrease in CF value. The pure spherical fly ash (CF = 1.0) produced lesser wear than fly ash having some angularity (CF = 0.91). Flow of sand particulate caused a highest erosion rate followed by bottom ash and fly ash.
