Introduction:
Gasexplosionsoccurduetotherapidreleaseandignitionofflammablegases,resultinginahighlyacceleratedcombustionprocess.Suchexplosionsproduceshockwavesthatcancausedestructiontonearbystructuresandendangerhumanlife.Theuseofpassiveprotectionsystems,suchasmetallicmesh,hasgainedattentionasapotentialmethodtosuppressthepropagationofshockwaves.Thispaperpresentstheexperimentalstudythatinvestigatestheeffectivenessofmetallicmeshinreducingtheimpactofgasexplosionshockwaveswithinpipes.
Methodology:
1.ExperimentalSetup:
-Atestrigisconstructedtosimulateagasexplosionscenarioinsideapipe.
-Pipesofsuitabledimensionsareselected,alongwithappropriatematerialsforconstructingthemetallicmesh.
-Ahigh-speedcameraandpressuresensorsareincorporatedtomeasureandanalyzeshockwaveparameters.
2.MeshConfiguration:
-Differenttypesofmetallicmesh,suchaswiremeshandperforatedplates,aretestedtoevaluatetheireffectivenessinsuppressingshockwaves.
-Themeshisstrategicallyplacedinsidethepipetodeterminethecriticalpositionsforoptimumshockwaveattenuation.
3.GasParameters:
-Differentgases,includingmethaneandpropane,areusedtostudytheimpactofvaryingexplosioncharacteristicsonshockwavepropagation.
-Theconcentration,pressure,andignitionmethodsofthesegasesarecontrolledandvariedsystematicallyduringtheexperiments.
