Can expanding the diameter of two-phase flow pipes reduce vibration and noise?

2017-04-25View Original

Thread Content

There is now a two-phase flow pipeline in which plug flow occurs. Some books suggest reducing the pipe diameter to transform the flow into annular flow in order to reduce vibrations, but after the diameter is reduced, the flow velocity exceeds the erosion velocity, which significantly shortens the service life of the pipeline. I would like to know whether it is possible to achieve the desired result by increasing the diameter so that the flow becomes laminar (a stable two-phase flow) Are there any other disadvantages besides the increase in investment? Thank you.
