Abstract
The importance of cockpit environment is generally overlooked, and detailed indoor related assessment is still limited in the existing literature. In this study, four numerical simulations were conducted using a Boeing 737 cockpit to investigate its air quality and thermal distribution. The thermal sensation of the pilots was assessed by comparing in-flight conditions (i.e. with and without window heat). Also, various indoor air-related indices were utilised to evaluate the ventilation performance and contaminant (CO2) removal under three ventilation configurations. The results demonstrated that window heat effect could significantly increase overall temperature (2 °C) and could lead to a severe thermal stratification from the pilots’ chest level. Current ventilation outcomes revealed that the air quality in upper region of the domain was not optimum, especially from pilots’ breathing level. The local contaminant removal in the human micro-environment was still ineffective even the personal gaspers were utilised. Potential health problems may occur.
