Analysis

Produce plots that characterize the temperature fields in the flames you study. Use this data to locate the flame front and determine how this is dependent upon the experimental parameters such as equivalence ratio and flow velocity.

Determine the experimental conditions for soot formation and discuss how a diluent inert gas alters this process. Can a flame temperature threshold be associated with the soot formation process? If so, determine this threshold and discuss why high or low temperatures are associated with soot formation.

The theoretical adiabatic flame temperature for a stoichiometric methane flame in air is 2200 K. Discuss why this is different from your measured values for the pre-mixed and diffusion flames.
