Abstract

Methanol is one of the strategic fuels to achieve the International Maritime Organization’s ambitious decarbonization goals over the next decades. As an expert in the marine sector, Alfa Laval is a leader in designing and supplying methanol fuel supply systems for marine diesel engines. In this study, Alfa Laval and EnginSoft present the results of a simulation of the methanol fuel supply system currently used on a methanol carrier. The scope of the study was to develop and validate a 1D computation fluid dynamics (CFD) model to reproduce the existing dataset collected from an actual system, in both steady-state and transient conditions, and its interaction with the upstream and downstream parts of the overall fuel line, from tank to engine. The validated model will enable Alfa Laval to simulate the system’s behavior under different conditions and to remotely support customers, forming the basis of a new digital approach to product development.

CASE STUDY

Large bore engine lubrication system: oil flow and pressure analysis using moving particle simulation

In this study, the focus was on the oil supply system for the big-end-bearings of an 18-cylinder engine, which is one of the largest four-stroke gas engines in existence, ideal for base load applications. Wärtsilä and EnginSoft created a moving-particle simulation model, a meshless method of solving Navier-Stokes equations, which allows complex geometries with moving parts to be simulated.
