Title:AnalysisoftheEvaporationCharacteristicsofDifferentComponentsofFuelDropletsunderSubcriticalCondition
Abstract:
Inthisstudy,weinvestigatetheevaporationcharacteristicsofdifferentcomponentsoffueldropletsundersubcriticalconditions.Theevaporationprocessoffueldropletsplaysacrucialroleinvariouscombustionsystemssuchasinternalcombustionenginesandgasturbines.Understandingtheevaporationcharacteristicsoffueldropletsisessentialforoptimizingcombustionefficiencyandreducingpollutantemissions.Inthispaper,weanalyzetheevaporationbehavioroffueldropletscontainingvariouscomponentstogaininsightsintotheirimpactoncombustionprocesses.
Introduction:
Thecombustionoffuelinvolvestheevaporationofliquidfueldroplets,mixingoffuelvaporwiththeoxidizer,andsubsequentcombustionreactions.Therateofdropletevaporationsignificantlyaffectsboththefuel-airmixingandtheoverallcombustionprocess.Hence,itisessentialtounderstandtheevaporationcharacteristicsoffueldropletsinordertoimprovecombustionefficiencyandreduceemissions.
Methods:
Toanalyzetheevaporationcharacteristicsofdifferentcomponentsoffueldroplets,weconductexperimentalinvestigationsusingahigh-temperatureandhigh-pressurechamber.Thechamberisequippedwithafuelinjectorthatcangeneratefueldropletsofvaryingcompositions.Theevaporationprocessisobservedandanalyzedusinghigh-speedimagingtechniques.Additionally,thetemperatureandpressureinsidethechamberarecontrolledtosimulatesubcriticalconditions.
