Abstract
At the preliminary design stage, the cabin layout of a certain aircraft requires the comfort assessment. The impact of “invisible” gaseous pollutants on passenger comfort during long flights cannot be ignored. Appropriate cabin layout helps control the spread of gaseous pollutants. First, for a certain aircraft, the structural digital model containing design details is cleaned, and the mesh is divided by a mixed grid. Second, the emission rate of CO2, O3, and VOCs is defined, and the position and speed of inlet and exhaust air are set. The Euler method calculates the flow field change caused by a cough of a passenger in the middle of the cabin and analyzes the diffusion range and concentration change trend of CO2 generated by the cough. Finally, the cabin layout is evaluated to control the diffusion range of gaseous pollution.
