Double Mask Efficiency vs. Aerosols (Flow Simulation) 二重マスクの空気中粒子対策効率
二重マスクの粒子捕集効果を調査した。計算流体力学（CFD）シミュレーションを用いて、異なるマスク構成の性能を評価した。結果、N95マスクと再利用可能なマスクの組み合わせが最も優れた粒子捕集効果を示した。This study has explored the effectiveness of double masking in filtering airborne particles. Using computational fluid dynamics (CFD) simulations, the study investigated how different mask configurations perform in preventing particle transmission. The findings reveal that a combination of N95 and reusable masks offers superior filtration, significantly reducing particle escape compared to other mask types.
