Looking For Pressure Drop Correlations Of Non-Newtonian Two-Phase Flow in The Pipeline
Looking For Pressure Drop Correlations Of Non-Newtonian Two-Phase Flow in The Pipeline
(OP)
Hi,
Can anyone guide me to have good correlations or equations to measure the pressure drop of non-newtonian two-phase flow in the pipeline?
Thanks

Various types of flow conditions can complicate the process, such as if significant temperature or velocity changes occur in the pipe's radial direction. That could result in slow flow against the pipe wall where cooler temperatures persist and high velocity in the central core where high temperatures may occur. In that case you may want to develop additional correlations to obtain an effective shear stress at that cross section.
You may be able to estimate the two phase flow behavior, after considering the above effeccts, but perhaps not. Nothing but the most basic pipeline profile would even approach an easy task.
You may find some additional help by researching further into the hydraulics of drilling well fluids. A number of correlations exist for two phase flows and nonNewtonian flows, but unfortunately not by area of expertise.
Whatever results you obtain, I would think that you will want to verify with extensive near full scale testing.
