Micro-Jet Ventilation (MJV), well-known as ventilation system in trains, was experimentally investigated under static flight conditions in a full-scale twin aisle cabin mock-up within the scope of the Clean-Sky 2 Joint Undertaking project ADVENT. With the aim to investigate ventilation systems for aircraft cabins with thermodynamically realistic boundary conditions, a jacket cooling was used to simulate real flight conditions. Temperature controlled thermal manikins (TMs) allow to simulate the heat release and obstruction of real passengers. In the present study, six different modifications of MJV with different air inlet configurations are analysed to find out optimal parameters for thermal comfort as well as energy saving. Fluid temperatures as well as velocities in the vicinity of the TMs were investigated using high-resolution local probes. An evaluation of the different MJV configurations was implemented by means of the heat removal efficiency, thermal comfort parameters and tracer gas analysis. The study clearly reveals almost optimal comfort parameters for two MJV configurations for future aircraft cabins.
