Abstract
The effect of flame position and its spatial variation on prediction accuracy of combustion oscillation in a dry low emission (DLE) combustor was studied. A one-dimensional linear model was developed. Methane was used as fuel and controlled by two thermal mass flow controllers. A triangular distribution function was introduced into the flame model because it is similar to the experimentally obtained distribution function. A "top-hat" distribution was also considered to test the influence of distribution shape on the result. The triangular flame model showed better prediction of the stability boundaries of combustion oscillation compared with the simple flame sheet model. The results of the top-hat flame model differed from those of the experiment. Consideration of the spatial distribution yielded good results for the DLE combustor. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
