N2 - This investigation proposed an innovative ventilation system that would reduce contaminant transport and maintain thermal comfort in airliner cabins. We manufactured and installed the proposed ventilation system in an occupied seven-row, single-aisle airliner cabin mockup. Air velocity, air temperature, and contaminant distribution were obtained by experimental measurements and were used to validate the results of CFD simulation. The validated CFD program was then used to study the impact of the locations and number of exhausts on contaminant removal and thermal comfort in a one-row section of a fully occupied Boeing-737 cabin. The air velocity magnitude was acceptable even in the leg area, and the proposed system provided an acceptable thermal environment in the cabin. The four-exhaust configuration of the new ventilation system was the best, and it decreased the average exposure in the cabin by 57% and 53%, respectively, when compared with the mixing and displacement ventilation systems.
