Two novel, ceiling-module integrated ventilation concepts are presented and experimentally analysed in a twin-aisle long-range cabin mock-up for different flight phases simulated by varied thermodynamic boundary conditions. Generally, the different supply techniques of LMCV and MJV reveal many similarities regarding mean flow fields and temperature distributions. However, local differences regarding higher flow velocities are found in the aisle region for MJV. A more detailed analysis based on studies with different mass flow ratios will be discussed at the conference. Moreover, the results regarding the analysis of the air quality level will be presented at the conference. Hereto, tracer gas measurements are carried out at the moment in order to determine local and global ventilation efficiencies.
