蒸汽-空气浸没射流压力振荡特性实验研究 Title:ExperimentalStudyonPressureOscillationCharacteristicsofSteam-AirImmersedJet Abstract: Thispaperpresentsanexperimentalinvestigationonthepressureoscillationcharacteristicsofasteam-airimmersedjet.Theprimarymotivationbehindthisstudyistounderstandthephenomenonofpressureoscillationinsteam-airimmersedjetsanditspotentialapplications.Theexperimentwasconductedbydesigningasetupthatallowedtheinjectionofasteam-airmixtureintoawatertank,andthepressurevariationswererecordedatvariouspositions. 1.Introduction: Steam-airimmersedjetshavegarneredsignificantattentionduetotheirpotentialapplicationsinindustriessuchaspowerplants,chemicalprocessing,andenvironmentalengineering.However,thepressureoscillationcharacteristicsofthesejetshavenotbeenthoroughlyinvestigated.Thisstudyaimstofillthisresearchgapandprovidevaluableinsightsintothebehaviorofsteam-airimmersedjets. 2.ExperimentalSetup: Aspeciallydesignedsetupwasconstructedtocarryouttheexperiment.Itconsistedofawatertankwithatransparentfrontpanel,asteam-airinjectionnozzle,apressuresensornetwork,andadataacquisitionsystem.Thesteamandairweremixedbeforebeinginjectedintothetank,andpressuresensorswereplacedatvariouspositionstocapturethepressurefluctuations. 3.Methodology: Theexperimentwasconductedbyvaryingthesteam-airmixturecomposition,injectionvelocity,andtankwaterlevel.Thepressureoscillationswererecordedatselectedlocationsfordifferentexperimentalconditions.Thedatacollectedwereanalyzedtodeterminethefrequency,amplitude,andcharacteristicsofthepressureoscillations. 4.ResultsandDiscussion: Theresultsrevealedthatthepressureoscillationsinthesteam-airimmersedjetexhibiteddifferentcharacteristicscomparedtoasingle-phasejet.Theoscillationfrequencyincreasedwithanincreaseinthesteamfraction,injectionvelocity,andwaterlevel.Moreover,theamplitudeofpressureoscillationswashigherattheinterfaceofthesteam-airjetandwater. 5.MechanismAnalysis: Tounderstandtheunderlyingmechanismbehindthepressureoscillations,adetailedanalysiswasconducted.Itwasfoundtha
