Abstract
Air velocity and temperature distributions in an aircraft cabin are calculated using 3-dimensional computation fluid dynamics code (STAR-CCM+). Calculation model is one row of sheets in an aircraft cabin (2 m in height, 1.25 m in half width, 0.8 m in length, and two passengers). Relations between air-conditioning conditions (air-inlet position, outlet position, inlet temperature, and velocity) and thermal comfort of passengers are examined. Air-inlet positions and outlet positions are examined at the ceiling, the upper sidewall, the lower sidewall, and the front sheet-wall. Calculation results show that the best condition is that two air-inlet positions at the front sheet-wall (2 m/s, 20-C) and the upper sidewall (10 m/s, 15-C).
