Particle-based CFD (computational fluid dynamics) methods have become very popular in recent years due to the simplicity of the model configuration process and the ability to solve free surface problems such as splashing.
One of the methods for free-surface problems is called moving particle simulation (MPS) and is frequently used in the automotive industry to evaluate splash patterns and churning losses in gearboxes.

CASE STUDY
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.
