  We study the flow structure in the jittering-jets explosion model of
core-collapse supernovae (CCSNe) using 2.5D hydrodynamical simulations and find
that some basic requirements for explosion are met by the flow. In the
jittering-jets model jets are launched by intermittent accretion disk around
the newly born neutron star and in stochastic directions. They deposit their
kinetic energy inside the collapsing core and induce explosion by ejecting the
outer core. The accretion and launching of jets is operated by a feedback
mechanism: when the jets manage to eject the core, the accretion stops. We find
that even when the jets' directions are varied around the symmetry axis they
inflate hot bubbles that manage to expel gas in all directions. We also find
that although most of the ambient core gas is ejected outward, sufficient mass
to power the jets is accreted (0.1Mo), mainly from the equatorial plane
direction. This is compatible with the jittering jets explosion mechanism being
a feedback mechanism.
