Abstract

Time-resolved volumetric pressure fields are reconstructed from Lagrangian particle tracking with high seeding concentration using the Shake-The-Box algorithm in a perpendicular impinging jet flow with exit velocity U = 4 m/s (Re ∼ 36, 000) and nozzle-plate spacing H∕D = 5. Helium-flled soap bubbles are used as tracer particles which are illuminated with pulsed LED arrays. A large measurement volume has been covered (cloud of tracked particles in a volume of 54 L, ∼ 180, 000 particles). The reconstructed pressure field has been validated against microphone recordings at the wall with high correlation coefcients up to 0.88. In a reduced measurement volume (13 L), dense Lagrangian particle tracking is shown to be feasable up to the maximal possible jet velocity of U = 16 m/s.
