The air conditioning system of most commercial aircrafts consists of a main system, which operates on the principle of mix ventilation, and a personalized system called gasper. Field studies show that passengers prefer to keep gasper parcially open or redirect it away from the head due to the discomfort. Therefore, there is a demand to characterize the flow of this device for future improvements. In this way, the present work aims to experimentally study the gasper jet inside a real cabin mockup using PIV. The results indicate that passengers are subjected to a high speed jet and the air in their breathing zone is mostly supplied by the mixed ventilation system due to the large entrainment ratio.

João Henrique Antoniazzi de Gouveia, University of São Paulo, Brazil

Graduated in Mechanical Engineering from Universidade Presbiteriana Mackenzie (2014). Current member and PhD studente at LETE (Laboratory of Environmental and Thermal Engineering) in the Department of Mechanical Engineering at Polytechnic School at University of São Paulo. From September 2016 to August 2017 I was a FUSP (Support Foundation for the University of São Paulo) scholarship for participating in the “Passenger Comfort Index Model” project, a project in partnership with Boeing. In this project, developed in the Mockup of an aircraft cabin at the CEC (Confort Engineering Center), I worked in the control of environmental parameters, such as temperature, humidity, noise and pressure during flight simulations.
