The paper presents a procedure for numerical simulation of the air permeability in the transversal direction of protective face masks. Two types of three-layer face masks were considered, and their air-permeability was experimentally measured together with the masks' structural, geometric and mass characteristics. Two simulation approaches were tested with the actual thickness of the mask (Model 1-1) and a scaled model, corresponding to 4 times augmentation of the mask's thickness (Model 1-4). A total of 12 steady-state simulations were conducted with a complete comparative analysis between the two models and the two masks (porous medium). An adapted ENGYS® version of the computational code OpenFoam® was applied. The numerical results were verified with the experiments and showed a very good correlation. [ABSTRACT FROM AUTHOR] |
