An experimental study was performed in a mockup of a Boeing 767 cabin section consisting of eleven rows with seven seats per row. The ventilation system for the mockup is constructed for actual aircraft components and includes linear diffusers that extend the full length of the mockup. Ventilation flow rates representative of an actual aircraft were used for all experiments. Seats in the mockup were occupied by thermal manikins to simulate passenger heat load. A motorized beverage cart traversed the length of the right aisle. Tracer gas and smoke visualization were used to determine the effect of the moving cart on transport of contaminants in the cabin. Carbon Dioxide (CO₂) tracer gas was injected at a constant flow rate at a location adjacent to the aisle until concentrations in the cabin reach steady-state.
