• Description:
  This study investigated aerosol transport inside a full-scale, 11-row, wide-body aircraft cabin mock-up, by quantifying an aerosol surrogate exposure. Cabin was supplied with fresh air through two supply air diffusers running along both cabin sides. Heated manikins simulated passenger thermal load. Tracer gas injected as an aerosol surrogate at breathing level at four different hypothetical contagious passenger locations was sampled radially up to 3.35 m from the source for 30 min per location. Twenty test pairs of different source and sampling locations were evaluated. The results confirmed source distance as the strongest exposure determinant. Average concentration at 3.35 m was 89% less than the source location. Concentrations were consistent in all directions at more distant locations but varied near the source due to cabin airflow patterns. In two tests, some concentrations further away from the source exceeded those near the source for a mid-cabin source, and a window seat source. [Description provided by NIOSH]
