Theproject involvestwosimulationmethodologies:directnumericalsimulation (DNS);and largeeddysimulation(LES)usingthefiltereddensityfunction(FDF)approach.DNSinvolvesminimalmodeling,butis restricted (by computational capabilities) to simple geometries and a moderate ranges of scales.LES/FDF involvesmoreextensivemodeling (and, therefore,uncertainty),but isapplicable topracticaldevicessuchas internalcombustionengines. Thegoalof theproject is toassessand to improve thecapabilitiesofLES/FDFbymakingdetailedcomparisonswithDNSofthesameflames.Theperformanceof the LES/FDFwillbe assessed via aposteriori comparisonswithDNS in turbulent lifted jet flames,premixedandstratifiedjetflames,andfuturesimulationsfocusingonbiofuelsfortransportationunderengineconditions(performedatSandiainarelatedEFRCproject).
