Abstract:
1. A method for determining flame blow-off conditions for a fuel-oxidant mixture in a combustor, comprising: selecting a plurality of cells from a region within said combustor; obtaining a plurality of Damköhler numbers in accordance with detailed combustion chemistry and detailed flow dynamics associated with each of said plurality of cells; providing an output representation associated with said Damköhler numbers; and determining flame blow-off conditions in accordance with said output representation, wherein each of said Damköhler numbers is obtained by dividing a chemical time by a residence time associated with each cell, wherein said residence time is selected in accordance with at least one of a mean flow residence-time value or a turbulent flow residence timescale value associated with a cell, and wherein said residence time is selected to be the minimum of said mean flow residence-time value and said turbulent flow timescale value.
