Application of Particle Image Velocimetry to measurement of flows on large scales is a challenging necessity especially for investigation of convective air flows in full scale aircraft mock-ups. The combination of high power quality switched solid state lasers as light sources with helium filled soap bubbles as tracer particles makes stereoscopic Particle Image Velocimetry on scales as large as 12.6 m2 possible. To fulfil the demand on high bubble generation efficiency concerning the bubble size and optimal distribution, a three channel bubble generator operating orifice nozzles was built in order to produce several thousand bubbles per second. The technique was applied to mixed convection in a full scale double aisle aircraft cabin mock-up. The experimental results were used for validation of computational fluid dynamic results of attendant Reynolds Averaged Navier-Stokes simulations provided by the DLR in-house code THETA.
