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

Siraj77,

Can you give the non-newtonian type you work?

Also, the pipe is horizontal or vertical?.

Napo.

Napo.

It's Xanthan gum solution, shear thinning fluid.
The pipe  is horizontal.

Thanks

Rheological Models for Xanthan Gum

Zhang Xuewu, Liu Xin, Gu Dexiang, Zhou
MO Yonghong Wei, Xie Tong.
ABSTRACT
The rheological behaviour of xanthan gum was determined at various temperatures (20-100°C) and concentrations (0.3-1.3%), and was found to be most adequately described by a power-law model. The effect of temperature on the viscosity followed an Arrhenius relationship, whereas the ef$ect of concentration followed an exponential relationship. A number of models to predict the viscosity as a function of shear rate, concentration and temperature are presented.
The models developed had an excellent fit and would be useful for manufacture and applications of xanthan gum.

Can you give me the pipe diameter and material in your test?.
