CFD investigation of solid–liquid two-phase flow in sewer pipes: influence of inlet slip velocity on particle resuspension

Key Points

• Particle resuspension significantly increases with higher inlet slip velocity, demonstrating a key relationship in flow conditions.
• The study highlights how variations in inlet slip velocity directly impact solid-liquid flow dynamics in sewer systems.
• Computational fluid dynamics simulations analyze a two-phase flow model, focusing on the interaction between liquid flow and solid particles.
• Understanding these interactions may lead to improved sewer system designs and management, particularly in handling solids.
