In this study, we evaluated the performance of three newly designed canisters for next-generation gas mask canisters using fluid analysis, including adsorption characteristics. We conducted breakthrough experiments in an adsorption bed to measure the adsorption kinetics of cyclohexane gas on activated carbon (ASC) and applied the obtained parameters to the fluid analysis of the Gas mask canisters.
We used granular and packed bed techniques to represent porous materials in CFD simulations. The CFD results were verified by comparing them with gas adsorption experimental results using the prototype canisters developed. We compared the breathing resistance and breakthrough time of the three gas mask canisters designed according to gas inflow conditions.
Furthermore, we conducted virtual engineering by applying CFD results to a VR system. The developed VR results provide gas mask canister design and optimization information. Using the CFD and VR results, we identified structural flaws in the optimal design of the gas mask canisters and provided ideas for a new canister shape.
In conclusion, this study comprehensively evaluates three newly designed purification systems for next-generation gas mask canisters using fluid analysis and adsorption characteristics. The use of CFD simulations and VR systems provides insights into the design and optimization of gas mask canisters, leading to the identification of structural flaws and the development of new design ideas. The findings of this study can contribute to the development of advanced purification systems for next-generation gas mask canisters that consider both user convenience and protective efficiency.
