Analysis of micro and nano particle erosion by the numerical method at different pipe bends and radius of curvature

ABSTRACT

The present study discusses the erosion of aluminium pipe using nano and micro particles. The Computational Fluid Dynamics (CFD) analysis using ANSYS-fluent is done for the prediction of the erosion. DPM model is used in CFD for erosion simulation. The analysis is done for the pipe bend angle in the range of 30–150° and the radius of curvature from 25 to 100 mm for both nano and micro particles. The test combinations and related CFD results are processed through Design of Experiments (DOE) – Response Surface Methodology (RSM) using Minitab tool. The micro particles show higher erosion compared to nano particles. Also it has been observed that, erosion depends mainly on Particle impact angle, Turbulence – secondary flow. The correlation is developed for the prediction of erosion at the given range.
