Zusammenfassung
Two papers have been prepared, reporting on experimental investigations
into the influence of water sprays on gas explosions. The water sprays
that were used in these experiments were produced by nozzles that
are very commonly used on offshore facilities. The experiments addressed
the influence of turbulence generated by these systems on the course
of gas explosions and the mitigating effect that water sprays may
have on gas explosions under certain circumstances. The second paper
reports on mitigation of gas explosions by water-spray systems. The
present paper reports on the influence of turbulence produced by
water sprays, investigated in a 1.5 m$^3$ rectangular box. The flame
speeds found in the presence of turbulence due to various types of
nozzles were approximately 1.4 to 2.3 times the flame speeds without
water sprays. The properties of the turbulence appear to be related
to the dimensions of the chamber in which the experiments were performed
and not to the dimensions of the droplets.
