Abstract

Surface roughness is known to have dominant impacts on a fluid flow, especially flows with high pressure drops such as the flows of crude palm oil (CPO). This study aims at analyzing the impacts observed in a pentagon spiral pipe to optimize energy consumption in CPO transport. In this study, a steady-state numerical analysis is performed in ANSYS-Fluent 19.2 software. Practically, a numerical analysis is conducted by simulating a pentagon spiral pipe using Navier-Stokes equations. Then, the effects of relative roughness and Reynolds number on drag reduction are investigated in the simulation. Looking at results of the simulation, this study highlights the importance of modelling the behavior of surface roughness effects at different temperature levels to discover better drag reduction impacts for improving efficiency in energy consumption for transporting CPO.
