The structure of turbulent noncondensing round and plane |
|
air jets submerged in still water were investigated |
|
experimentally. Both adapted and underexpanded jets were |
|
considered, the latter with underexpansion ratios up to |
|
8:1. Measurements included flow visualization, using |
|
flash photography and shadowgraphs as well as high-speed |
|
motion-picture photography; mean void fraction |
|
distributions, using gamma-ray absorption; entrainment |
|
rates, using laser-Doppler aneomometry; and mean static |
|
pressures, using static-pressure probes. Present |
|
measurements and the earlier results of Bell et al. |
|
(1972), Tross (1974) and Carreau et al. (1985) were used |
|
to evaluate analysis of the process. The analysis was |
|
based on the locally-homogeneous-flow approximation |
|
(relative velocities between the phases neglected) and |
|
the effective-adapted-jet approximation for underexpanded |
|
jets. Keywords: Multiphase flow, Gas jets, Liquids, |
|
Compressible turbulent jets. |
