The performance of personalized ventilation combined with local suction at each seat was studied for the purpose of minimizing airborne cross-infection in vehicle compartments. Experiments were carried out in a simulated aircraft cabin section (3 rows, 21 seats). One breathing thermal manikin simulated “infected” polluting passenger and another simulated “exposed” passenger. Personalized ventilation supplied clean air at 10 L/s from front against manikins’ face. Air was sucked at 10 L/s by a suction system of two nozzles positioned on the sides of “infected” manikin’s head. The cabin was ventilated at 180 L/s. The concentration of Freon mixed with air exhaled by the “infected” manikin was measured. The personalized flow pushed the contaminated exhaled air backwards where it was pulled by the suction and exhausted before mixing with the cabin air. This resulted in substantial decrease of the tracer gas concentration in the air inhaled by the “exposed” manikin and the exhausted cabin air.
