The combustion process in automotive engines requires clean and dry air, making efficient water separation in the air intake system critical. Depending on water droplet size and velocity, water can be either separated and drained or enter the air intake system. A reliable numerical methodology for predicting water droplet behavior in the air intake system is essential for optimizing intakes prior to prototype construction.
To achieve this goal, a multiphase model in the CFD software STAR-CCM+ was explored. Additionally, ParticleWorks software was used for a comprehensive study. The investigation comprised multiple smaller studies, culminating in a detailed analysis of the full model under various conditions.
A comparison between steady state and unsteady state analyses using the LMP model in STAR-CCM+ was conducted, with the steady state model proving more suitable for the application. Furthermore, this model was compared with a ParticleWorks model using the MPS model, showing the latter to be inadequate.
The research concluded with a correlation to a real test performed by CNH Industrial, validating the developed methodology's reliability.
