Air along with sand particles of density 1500kg/m3 and 50 micron in diameter are used in this analysis with mass flow rate is 1kg/in. A180 degree bend is numerically simulated using FLUENT 6.2. The meshing software used is GAMBIT2.2. The Discrete Phase Model is used for analyzing the erosion due to particle impacton a three dimensional 180 degree U-Bend with pipe diameter of 0.50inches. Erosion in U-Bend is acommon phenomenon in pneumatic conveyor and other fluid handling equipment’s. The turbulent flow structures are investigated. And them agnitude and location of erosion in a U- Bend determined.
