Sinusitis disease has become widespread lately. Warming the sinus area with a face mask may prevent sinusitis disease, which may occur due to the presence in a place colder than body temperature especially on a cold morning day. This paper proposes experimentally the creation of a transparent facemask prototype that can maintain warmth in both the maxillary and frontal sinus areas. It contains an overlap volume to improve temperature, CO2 and H2O comfort. Furthermore, a two-dimensional numerical study is provided by Ansys® FLUENT 2020 R1 Computational Fluid Dynamics (CFD) simulations using RNG (ReNormalization Group), k-ɛ turbulence model. It predicts flow characteristics of velocity, temperature, and mass fraction of CO2 and H2O distributions during 28 breathing cycles. This approach is validated by comparing its results with previous studies and the experimentally measured results for temperature using an Arduino Temperature sensor at a selected point within the experimental prototype. The mean temperature values rise to reach a steady-state for both numerical and experimental study. The CO2 and H2O concentrations inside the mask are very small. The results confirm that the mask achieves its purpose in warming nasal and sinus areas.

Lately, sinus disease has become prevalent. Sinus disease that may arise due to the presence in a location colder than body temperature can be avoided by warming the sinus region with a facemask. This paper presents the design and development of a facemask that can maintain warmth in the nasal area and sinuses. To maximize temperature comfort, it includes a volume overlap. A two-dimensional numerical analysis to predict flow characteristics of velocity and temperature distributions during breathing cycles is provided using Ansys ® FLUENT 2020 R1 Computational Fluid Dynamics (CFD) simulations. Findings approve that the mask achieves its aim in warming nasal and sinus areas.
