Flame acceleration study using obstacles and its application in spark-ignition engines
thesis
posted on 2013-12-03, 14:25 authored by Venkatesan ThyagarajanBurn rate in homogeneous premixed charges can be enhanced by
flame acceleration caused by turbulence generated in the flow
field and distortion of the flame front, by placing obstacles in
the path of the propagating flame front.
The work presented here makes use of the above phenomenon of
using obstacles to enhance burn rate in spark-ignition engines.
From the evaluation of heat loss to work done ratio and from
constant volume combustion bomb experiments the obstacled surface
has been optimized.
The applicability of the optimized surface has been demonstrated
by single cylinder engine tests, the results of·which show
improvement in engine performance and has been compared with
published data of a commercial I.D.I. engine.
