Abstract: | The gas entrainment in a hollow cone spray submitted to variable density is studied experimentally in order to better understand
the effect on mixture formation. Particle image velocimetry on fluorescent tracers, associated with a specific processing
of the instantaneous velocity fields have been applied to obtain measurement in the close vicinity of the spray edge. In the
“quasi-steady” region of the spray, important effect of the ambient density on the mass flow rate of entrained gas
have been pointed out. The axial evolution of is in good agreement with an integral model that takes the momentum exchange between phases into account. |
