Abstract
Micro-Jet Ventilation (MJV), known from ventilation systems in trains, was experimentally investigated under static flight conditions in a full-scale twin-aisle cabin mock-up as part of the Clean-Sky 2 Joint Undertaking project ADVENT. A jacket cooling system was used to investigate ventilation systems for aircraft cabins with thermodynamically realistic boundary conditions. Temperature-controlled thermal manikins (TMs) make it possible to simulate the heat dissipation and obstruction of real passengers. In this study, six different modifications of MJV with different air inlet configurations are analyzed to determine the optimal parameters for thermal comfort and energy savings. Fluid temperatures as well as velocities in the vicinity of the TMs were investigated using high-resolution local probes. An evaluation of the various MJV configurations was performed based on heat removal efficiency, thermal comfort parameters, and tracer gas analysis. The study clearly shows the near-optimal comfort parameters of two MJV configurations for future aircraft cabins.
