Intuitional experiment and numerical analysis of flow characteristics affected by flow accelerated corrosion in elbow pipe system

• Wall-thinning erosion of pipelines in plants leads to fatal accidents unexpectedly.
• Flow Acceleration Corrosion (FAC) is a main reason of wall-thinning.
• For industrial safety, it is necessary to verify the tendency of FAC.
• We focused on local wall thinning by FAC with intuitional visualization experiment and numerical analysis in elbow pipe.
