Prediction of pipe geometry influenced by various suction pressure

Abstract

There are two main types of fuel pipes, and each is categorized according to the maximum pressure it can withstand. The main purpose of low-pressure pipes is to transfer fuel from a storage tank to a service tank and then, via a feed pump, to injection pumps. Fuel from an injection pump is delivered through high-pressure pipes to the engine's combustion chamber. The current work is concerned with low pressure pipes to determine the pressures at the inlet and outlet of diesel pipes of various cross sections used to transport diesel to the ships. Circular and rectangular cross-sectional pipes are considered for the present study, and the influence of geometrical factors is estimated on the inlet and outlet flow parameters of diesel fuel using Fusion 360/CFD software. The variations in the pressure, velocity of the fuel, and shear stress in fuel-carrying pipes in all planes are presented. The rectangular-shaped pipe generated more shear stresses than the circular cross-sectional pipe. Further, different-shaped circular pipes are designed and tested for temperature distribution in the pipes while carrying the diesel fuel. The present work is used for the effective design of diesel-carrying pipes from the bottom to the top end from the perspective of suction pressure.
