N2 - This paper presents a benchmark performed in the frame of
the SARNET-2 EU project, dealing withmomentum transfer
between a real-scale PWR spray and the surrounding gas.
It presents a descriptionof the IRSN tests on the CALIST
facility, the participating codes (8 contributions),
code-experiment andcode-to-code comparisons. It is found
that droplet velocities are almost well calculated one
meter belowthe spray nozzle, even if the spread of the
spray is not recovered and the values of the entrained
gasvelocity vary up to 100% from one code to another.
Concerning sensitivity analysis, several
'simplifications'have been made by the contributors,
especially based on the boundary conditions applied at
the locationwhere droplets are injected. It is shown here
that such simplifications influence droplet and entrained
gascharacteristics. The next step will be to translate
these conclusions in terms of variables representativeof
interesting parameters for nuclear safety.
