Spark ignition phenomena have been studied from various viewpoints in
the context of premixed flames.
Relatively little has been done on the spark ignition in the context of
non-premixed combustion.
Spark ignition of inhomogeneous gaseous or gas-droplet mixtures has
applications in aviation gas turbine relight and
direct injection engines. We explore the fundamentals of ignition
processes by experiments and Direct Numerical Simulations (DNS).
Modelling of this process is also carried out with the Conditional
Moment Closure (CMC) in the context of
Reynolds Averaged Navier Stokes (RANS) simulation.
