Thesis
Mathematical modelling of combustion in confinement and autoignition
- Abstract:
-
Knock in spark-ignited internal combustion engines is a result of an explosion, known as autoignition, in the unburnt end-gas ahead of the flame. Autoignition is first apparent at hot spots, which develop suddenly at localised points in the end-gas after a period of seemingly normal combustion. We use perturbation methods to analyse a one-dimensional model of premixed gaseous combustion in confinement, to demonstrate the role acoustic waves play in the development of hot spots.
