Monday 28 May 2012: Stability of jets in Diesel engines
Dr Matt Turner, University of Surrey. -
Harrison 170 15:00-16:00
This talk focusses on the stability of jets, with particular
focus to fuel jets in Diesel engines. CFD simulations of jet and spray
penetrations in Diesel engines use the stability theory of jets to
determine break-up times, and break-up lengths. However it is found that
these current CFD approaches underestimate the break-up lengths by a
large amount, so the effects of acceleration are believed to be
important. This talk concentrates on steady jets to try to understand
the fundamental stability processes in these jets, so this theory can
then being applied to unsteady jets.
