In the present world of constant redevelopment and construction, the amount of dust freely floating in the air near major streets and roads are extremely high and inconsistent which can lead to filtration products not performing as per requirement.

The study aims to develop a CFD methodology to simulate the Dust Holding Capacity (DHC), Filtration Efficiency and understand Dust particle behaviour when it flows through a 2W Air intake Assembly. The Dust that is present in the air is of various compositions, sizes, shapes etc and these properties of the dust effect the behaviour when it floats through the air. A primary performance evaluation factor for Air Filter assembly is the Dust holding capacity, which also decides the service interval for the filter element along with filtration efficiency.

Our goal for this study is to develop a CFD methodology by which both DHC and efficiency can be evaluated for a Filter Assembly and results are going to be verified using Test Bench data. Filtration of particles based on particle size will also be used to accurately predict how much of the dust particle will be captured by the filtration media. From this study we hope to prepare a robust methodology to setup air filter assemblies using CFD to predict DHC and Filtration efficiency which will help us develop better and more efficient products resulting in lower vehicle emissions and reduced wear and tear of critical engine internal components..
