Instability of plane Couette flow under competing effects of viscoelasticity and vertical throughflow

Key Points

• Instability arises from the interaction between viscoelasticity and vertical throughflow, impacting fluid behavior.
• Key evidence shows that increasing viscoelastic effects alters flow stability significantly.
• Observational analysis of fluid mechanics models indicates that both parameters need to be considered together.
• Highlights the complexity of fluid dynamics, calling for more integrated models to predict behaviors.
