The qualitative comparison between experiments and CFD simulations showed satisfactory agreement and is providing a basis for improving erosion models for these flow conditions. erosion pattern concentration production...

... ABSTRACT As production takes place in the petroleum industry, impurities are produced along with oil and gas. Sand is a common impurity associated with production. If sand is present, it is desirable to have continuous flow of even small concentrations of sand through the pipeline to avoid...
