Using aerosols to create Nano-scaled membranes that improve gasoline particulate filter performance and the development of Wafer-based membrane coated filter analysis (WMCFA) method

Weiqi Chen et al.

Summary: This paper investigates the use of artificial aerosols to synthesize nano-scale membranes that mimic the soot cake in diesel particulate filters (DPF) for gasoline direct injection (GDI) engines. The experiments demonstrate that membranes produced with larger aggregate size particles or under lower face velocity yield better performance in terms of filtration efficiency and pressure drop.

Impacts of catalyst coating on the filtration performance of catalyzed wall-flow filters: From the viewpoint of microstructure

Qiang Lyu et al.

Summary: The study investigated the influence of catalyst coating on the filtration performance of silicon carbide (SiC) filter cores, finding that the coating significantly decreased the initial filtration efficiency and led to faster increases in filtration efficiency and pressure drop over time in the deep-bed filtration regime. Analysis revealed that the catalyst is preferentially deposited in smaller pores, reducing pore volume for relevant filtration pores, and wiping out a group of smaller pores. The study provides a working mechanism to explain the decreased filtration efficiency on catalyzed filters based on experimental and characterization data.

High fidelity simulation of ultrafine PM filtration by multiscale fibrous media characterized by a combination of X-ray CT and FIB-SEM

Zhengyuan Pan et al.

Summary: This study successfully reconstructed a three-dimensional digital model of nanofiber-based filter media using advanced characterization technologies and modular simulation models, and conducted filtration simulations that agreed well with experimental results. The structure-resolved models showed higher accuracy but also higher computational costs, while unresolved simulations tended to overpredict filtration efficiency.

Effect of main-stage filter media selection on the loading performance of a two-stage filtration system

Xinjiao Tian et al.

Summary: This study experimentally evaluated the performance of a two-stage indoor air filtration system, focusing on the selection of main-stage filter media. The effectiveness of adding a pre-stage filter media was found to be significantly influenced by the incoming aerosol size distribution. It was also observed that different types of main-stage filter media reacted differently to the presence of a pre-stage filter.

Digital Twin Geometry for Fibrous Air Filtration Media

Ivan P. Beckman et al.

Summary: This study showcases the possibility of computational modeling of air filtration by replicating nonwoven nanofibrous meltblown or electrospun filter media with digital representative geometry. The methodology presented in this article allows the creation and modification of randomly generated fiber geometry intended as a digital twin replica of fibrous filtration media. The study also incorporates the use of the Single Fiber Efficiency model to estimate the performance of the generated media with an analytical model.
