Test Details

• Chemiluminescence signatures of OH^* and CH^*.


• Determination of marker for equivalence ratio.


• Determination of marker for flame temperature.

CH^* chemiluminescence and flame temperature

• CH^* intensity and temperature variations with equivalence ratio are similar.


• However, CH^* and temperature peaks do not occur at same equivalence ratio.


• Hence, CH^* might not be a good marker for flame temperature.

OH^* chemiluminescence and flame temperature

• OH^* intensity and temperature variations with equivalence ratio are similar.


• Further, OH^* and temperature peaks occur at nearly same equivalence ratio.


• Hence, OH^* is a good marker for flame temperature.

OH^* intensity-flame temperature correlation

• OH^* intensity normalized using its peak value and temperature variations are correlated using the following expression (R² = 0.97).


• The correlation is based on data obtained for ? = 0.85-1.35.
