Movement of natural sand particles (d=200−300 μm) in a simulated atmospheric boundary layer was visualized using a digital high-speed camera. The consecutive particle images recorded at 2000 fps (frame per second) enabled us to observe the particle transport in detail, especially near the flat sand surface. Various modes of sand saltation were identified. The transverse motion of particles, often...
The flow characteristics around a rotating axial fan were experimentally investigated using a phase-averaged PTV velocity field measurement technique. The axial fan has 5 forward-swept blades with a radius of 25 mm. Measurements were carried out at 4 axial planes and 4 radial planes perpendicular to the axis of rotation. For the axial plane measurements, one fan blade was divided into 4 different...
