The change in pressure gradient and liquid holdup across the intermittent to segregated transition is more pronounced at low v SL . In segregated flow, the pressure gradient ( -dp/dL ) increases with pressure...

... Abstract Slug liquid holdup is one of the most important parameters of slug flow. It is closely related to the average liquid holdup and pressure gradient of slug flow in wells and pipelines. Barnea and Brauner (1985) and Zhang et al. (2003a) mechanistic models are based on the turbulent...

... diameter of the pipe is 52.5 mm (2.067 in). The experimental measurements include pressure gradient and liquid holdup. The flow pattern and slug characteristics are observed and the images are recorded with a high definition video system through a sapphire window. The experimental results are compared...

... Abstract The liquid holdup distribution and pressure drop of a wire mesh demister was investigated experimentally. The meshpad porosity was 98.06 vol % and the height 0.1m. It was tested at ambient conditions with air and water. The liquid holdup inside the mesh pad was measured at five...

...-dimensional model offers detailed flow distributions that are impossible to obtain with one-dimensional models. It was demonstrated recently that flow regime transitions, observed pressure gradients and liquid holdup can be accurately reproduced (Laux et al., 2007). In the present paper, we analyze 2-phase...
