Abstract

Face masks are used to trap particles (or fluid drops) in a porous material (filter) in order to avoid or reduce the transfer of particles between the human lungs (or mouth and nose) and the external environment. The air exchange between the lungs and the environment is assumed to occur through the face mask filter. However, if the resistance to air flow through the filter is high some air (and accompanied particles) will leak through the filter-skin interface. In this paper I will present a model study of the side-leakage problem.

口罩侧漏

摘要

口罩用于将颗粒（或液滴）捕获在多孔材料（过滤器）中，以避免或减少颗粒在人体肺部（或口鼻）与外部环境之间的转移。假设肺部和环境之间的空气交换是通过面罩过滤器进行的。然而，如果通过过滤器的气流阻力较高，一些空气（以及伴随的颗粒）将通过过滤器-皮肤界面泄漏。在本文中，我将提出侧漏问题的模型研究。
