Effects of consistency and shear-thinning indices on interfacial wave dynamics and roughness in vertical annular flows

Key Points

• Interfacial waves exhibit distinct dynamics under varying shear-thinning conditions, enhancing flow understanding.
• Key metrics consider both wave characteristics and surface roughness aspects during fluid movement.
• Analysis of fluid dynamics employs a detailed examination of vertical annular flows across diverse conditions.
• Findings may enable improved design strategies in applications involving fluid flow in pipes and channels.
