title = "Can gaspers provide protection from airborne contaminants to the occupants in an airliner cabin?",
abstract = "Gaspers are designed for regulating thermal comfort in airliner cabins. But it is not clear if gaspers can provide protection to passengers against airborne contaminants. The present study investigated the airflow from the gaspers in conjunction with the main supply in a single row section of a twin aisle, fully occupied airliner cabin. The investigation used the Computational Fluid Dynamics (CFD) method with the RNG k-ε turbulence model. A highly refined mesh with 15 million tetrahedral elements was used to capture the high velocity air jets. The predicted centerline velocity profile and entrainment were in agreement with the available experimental data. It was found that the fraction of the gasper air became smaller with the distance from the gaspers and was around 10% in the breathing zone of the passengers. The risk reduction of the case with the gaspers was not significant compared with the case without the gaspers.",
