Analysis of Fluid Flow on the N95 Facepiece Filtration Layers

Due to the general confusion over mask's efficiency against COVID-19 virus droplets, professionals and public may find it difficult stop disease from spreading. This study intends investigate fluid flow across N95 filtration layer based on experimental data create a simulation model analysis. Therefore, is simulated using ANSYS Fluent, part of Computational Fluid Dynamics (CFD) solver software. anticipates by porous media approach, in which inertial resistance viscous are introduced obtaining pressure drop coefficient actual 3M filtration. The passed through with some velocity range MS 2323:2010 standard. distribution analyzed illustration contour streamline fluid. For most conditions, as flowed filter, gradually began retard diverge around layer. Besides, different rates also result distributions To sum up, this beneficial forecasting behavior applying zone approach simulation.
