Ethanol is considered an alternative fuel and can be used to replace fossil fuels. In order to investigate the behavior of ethanol as a fuel, some of its combustion properties are measured and characterized, such as laminar burning velocity and flame front stability, which strongly depend on the appearance of cellularity on the flame, therefore the objective is to characterize the combustion process of ethanol flames under cellular conditions.
After some preliminary tests, two-factor polynomial models up to order three are considered, depending on the pressure of the combustion chamber and the fuel/air equivalence ratio. A comparison study between the D- and I-optimal designs is performed, choosing finally the I-optimal design for the experiment, testing and the development of predictive models for the response variables. Images confirm that fitted models predict correctly the response variables, and the predictions are in accordance with the results obtained by other works.
