چکیده
|
The volume of fluid (vof) model together with the continuum surface stress (css) model is proposed to simulate the core annular of non-newtonian oil and water flow through the rectangle return bends (π-bends). a comprehensive investigation is conducted to generate the profiles of volume fraction, pressure and velocity. the influences of oil properties, flow direction, and bend geometric parameters on hydrodynamic of non- newtonian oil and water core annular flow in π-bends are discussed. through computational simulations the proper bend geometric parameters were identified, these results are useful for designing and optimizing the pipefitting system.
