Erosion Analysis of Coal Mine Pipeline Valves at Different Opening Conditions

Solid particulates carried with the flow in pipeline can be potentially erosive to many engineering materials used for coal mine pipeline components. Sometimes slow removal of acidic mine water may cause deposition of the yellow body material in coal mine pipeline components followed by corrosion. Various models have been developed to predict erosion rates in various complex geometries of valve. In this study computational fluid dynamics (CFD) based erosion prediction model in the ANSYS-FLUENT is used to find out the erosion behaviour of the butterfly and ball valves in different opening (i.e. operating) conditions. The erosion rates are obtained for valve angles 40°-90° for butterfly valve and 10°-60° for ball valve.
