| Zusammenfassung |
| An oscillating grids
turbulence generator was constructed for studies of two new effects
associated with turbulent transport of particles, turbulent thermal
diffusion and clustering instability. These effects result in formation of
large-scale and small-scale inhomogeneities in the spatial distribution of
particles. The advantage of this experimental set-up is the feasibility to
study turbulent transport in mixtures with controllable composition and
unlimited observation time. For flow measurements we used Particle Image
Velocimetry with the adaptive multi-pass algorithm to determine a
turbulent velocity field and its statistical characteristics.
Instantaneous velocity vector maps, flow streamlines and probability
density function of velocity field demonstrate properties of turbulence
generated in the device. |
