To facilitate this investigation, a dedicated experimental setup capable of generating nearly homogeneous and isotropic turbulence (HIT) using the interaction of eight water jets within a cylindrical water tank was built. The 3D trajectories of particles inside the tank is tracked using a three-camera Particle Tracking Velocimetry (PTV) system. This experimental apparatus was specifically designed to fit within the Dryden Drop Tower at Portland State University, where 2.1 seconds of microgravity can be achieved.
During this presentation, experimental findings regarding the Lagrangian dynamics of particles in microgravity will be discussed.
