COMBUSTION FUNDAMENTALS

COMBUSTION FUNDAMENTALS. Turbulent Premixed and Non-Premixed Flames. EXAMPLE: SPARK IGNITION ENGINES. Even though fuel is introduced as a liquid, spark-ignition engines fuels are highly volatile, and liquid has time to vaporize and thoroughly mix with air before mixture ignited by spark

Laminar Premixed Flames

Laminar Premixed Flames. A flame represents an interface separating the unburned gas from the combustion products. A flame can propagate as in an engine application or be stationary as in a burner application. For a given P, T, f and laminar conditions a flame has two basic properties:
