High-Pressure Gas-Liquid Flow Driving Force for Momentum

High-Pressure Gas-Liquid Flow Driving Force for Momentum

(OP)
Hi all,

Just a couple quick questions regarding an assignment I'm working on in relation to petroleum production systems.

- In high-pressure gas-liquid flow, what phase provides the driving force for momentum? What does this mean about the velocity of that phase as it moves along the pipeline?
- Which aspect of shutting down the flowline at high pressure increases flow assurance risk the most?
- Interfacial tension describes the energy penalty of creating an interface between immiscible phases?

Thank you all for your time.
