Computational Investigation on Multiphase Flow Behavior of Newtonian and Non-Newtonian Fluids

Abstract

This work investigates heat transfer in two–phase flow of Newtonian fluid (water) and power-law non-Newtonian fluid (polycarbonate) in a T-shaped cylindrical geometry. The problem is simulated using Computational Fluid Dynamics (CFD) techniques, specifically the Level Set interface tracking method. Focusing on pressure, velocity and temperature distributions under different flow conditions, the research addresses challenges related to computing efficiency, numerical stability, and interface dynamics. These findings lay a foundation for optimizing fluid system by illustrating how flow parameters affect phase interactions and pressure gradients.
