Due to extremely time consuming simulation
s
for three
sector configuration the spark parameters
(location and size) are chosen such to guarantee successful ignition in selected sector.
Basing on previous experiments performed for single sector case the spark
was
located
close to
the edge of the recirculation zone, the size of the spark
was
equal to 15 mm.

ignition (flame propagation)) took more
