Numerical Simulation on the Effect of Blade Design Towards Pressure and Velocity in Pipeline

Abstract

Since natural gas (NG) now accounts for 20% of the world’s primary energy needs, the demand for gas is expected to increase by a total of 140 billion cubic metres (bcm) between 2021 and 2025. NG also referred to as wet gas is mostly made up of methane with traces of other molecules; if left untreated, it will cause several operational issues. An environmentally beneficial method of processing natural gas is the inline centrifuge separator, which is one way to recover parameter-free water and NG stream without using any chemicals or inhibitors to stop hydration formation from happening. The inline centrifuge hydrate inhibitor, however, offers improved possibilities for preventing hydration while providing a straightforward design, low production cost, and excellent efficiency. RNG k–ɛ is turbulent, and mixed multi-phase models were connected during the conceptional design stage to determine flow behaviour using computational fluid dynamics (CFD). Computational methods for developing and improving products are used in this way. The purpose of this work is to investigate and simulate the impact of flow characteristics such as pressure and velocity from the proposed blade. The results of the numerical simulation showed that the blade tended to produce the closest results from the validation design decreasing from 40.5 to 37.9 kPa.
