Abstract:
Two-phase flow implies to the simultaneous movement of two separate phases, such
as gases-liquids, liquids-solids, or gases-solids depending on their applications in
energy, oil and gas, and chemical processing. This includes slug, bubbling, churn, and
mist flows, among others. These flows are modeled using techniques such as the
Phase Field Approach, Finite Volume Method, and Euler-Euler model utilizing
computational fluid dynamics (CFD) software, COMSOL Multiphysics. This study
attempts to examine the laminar two-phase flow of Newtonian (water) and nonNewtonian fluids (polymer using the Carreau model) in a cylinder. Specifically, the
goal is to understand the velocity distribution, pressure profiles, and volume fraction
distribution and the complicated relationships that exist between Newtonian and nonNewtonian fluids in constrained geometries, relationships that are essential for the
optimization of a variety of industrial processes.
