Experimental Investigation of Solid Particle Erosion in S Bend

Abstract

Solid particle erosion is a micromechanical process that removes material from the surface. Erosion is a leading cause of failure in fluid handling equipment such as pumps and pipes. An investigation was conducted using an Sbend geometry with 12.7 mm inside diameter, r/D ratio of 1.5 with three different air velocities and two different particle sizes. This paper presents the preliminary results of an investigation to determine the location of erosion for a wide range of conditions. The experimental results showed the location of maximum erosion at 29–42 deg from the inlet at 45.72 m/s air velocity with 300 خ¼m particle sizes.
