Simulation Study on the Impact of Porous Media Microstructure on Gasoline Particulate Filter Performance

<div class="section abstract"> <div class="htmlview paragraph">Stricter environmental legislation is driving ever-more-demanding performance targets for gasoline particulate filters (GPFs). This study constructs a multi-scale filtration model based on fractal characteristics, taking into account particle size distribution and particle deposition, to investigate the influence of the microstructure of porous media on GPF performance and analyze the impact of structural parameters on ca
