The Importance of High-Frequency, Small-Eddy Turbulence in Spark Ignited, Premixed Engine Combustion
(1995) SAE Fuels & Lubricants Meeting and Exposition- Abstract
- The different roles played by small and large
eddies in engine combustion were studied.
Experiments compared natural gas combustion in a
converted, single cylinder Volvo TD 102 engine and in
a 125 mm cubical cell. Turbulence is used to enhance
flame growth, ideally giving better efficiency and
reduced cyclic variation. Both engine and test cell
results showed that flame growth rate correlated best
with the level of high frequency, small eddy turbulence.
The more effective, small eddy turbulence also tended
to lower cyclic variations. Large scales and bulk flows
convected the flame relative to cool surfaces and were
most important to... (More) - The different roles played by small and large
