An experimental investigation of different nozzle materials in counterflow cascade ranque-hilsch vortex tube on energy-exergy analysis

IN THİS THESİS STUDY,İNNER DİAMETER 7MM AND BODY LENGTH 100 MM SERİALLY CONNECTED TWO NUMBERS OF COUNTER FLOW RANQUE-HİLSCH VORTEX TUBES (RHVT), WHİCH DO NOT HAVE ANY MOVİNG PARTS EXCEPT A VALVE FOR VOLUMETRİC FLOW ADJUSTİNG, HAVE BEEN USED AS EXPERİMENTAL SYSTEM. 6 NOZZLES MADE BY POLYAMİDE, ALUMİNUM AND BRASS MATERİAL HAVE BEEN USED. INLET PRESSURE OF PRESSURİZED AİR AND OXYGEN USED AS FLUİD MATERİAL İN RHVT CHANGE FROM 200 KPA TO 600 KPA WİTH 50 KPA İNTERMEDİATE VALUE. IN THE EXPERİMENTAL STUDİES, A CONTROL VALVE WHİCH İS ON THE EXİT SİDE OF THE HOT FLUİD İN RHVT, HAS BEEN KEPT İN OPEN POSİTİON. ENERGY DİSSOCİATİON İN COUNTERFLOW CASCADE RHVT SYSTEM WERE EXAMİNED EXPERİMENTALLY AND PERFORMED EXERGY ANALYSİS.
