  We investigate the collision of a continuous liquid jet with a regular stream
of immiscible droplets. The immiscible liquids, namely silicon oil for the
continuous jet and an aqueous glycerol solution for the drop stream, are
selected to enable the total wetting of the drops by the jet liquid. Four
different regimes are experimentally identified: drops in jet, encapsulation
without satellites, encapsulation with satellites from the jet liquid and mixed
fragmentation. The drops in jet regime, potentially of great interest for new
applications, corresponds to a regular stream of drops embedded in a continuous
jet and is described and reported for the first time. Using well known aspects
of drop collision and jet stability, we propose to model the transition between
the drops in jet regime and the others. Two dimensionless parameters are
derived from this analysis which are thus used to produce a simple regime map
where the drops in jet regime can be well distinguished from the other
outcomes.
