Abstract:

“AbstrakVortex tube yang dikenal dengan nama Ranque Hilsch Vortex Tube (RHVT) adalah sebuahalat sederhana tanpa ada komponen yang bergerak di dalamnya yang memisahkan udaramasuk yang bertekanan menjadi dua aliran terpisah yaitu udara panas dan udara dingin secarabersamaan pada masing–masing keluarannya. Proses pemisahan dua aliran dimana yang satumenjadi aliran dingin dan yang satu menjadi aliran panas bisa ditinjau sebagai prosespemisahan energi. Teori mengenai proses pemisahan energi umumya didapat dari hasilexperiment dan sebagian dari simulasi numerik. Paper ini membahas mengenai phenomenapemisahan aliran dingin dan panas di dalam RHVT jenis counter flow pada tekanan udaramasuk ke nosel sebesar 2 atm dengan jumlah nosel 2 buah. Kajian dilakukan secara numerikmenggunakan perangkat lunak komputasi dinamika fluida Fluent. kajian numerik inimenggunakan model aliran viscous Kappa Epsilon (k-e) dengan domain komputasi 3D. Hasilsimulasi numerik properties fluida ditampilkan dalam bentuk visualisasi kontur, vektor dan garisalir kecepatan axial, kecepatan radial dan juga aliran sirkulasi balik beserta distribusi tekanandan temperatur yang terjadi didalam tabung vorteks. Kinerja RHVT ditunjukan oleh kurvaselisih temperatur udara masuk dengan temperatur udara keluar dingin ?Tc terhadap fraksimassa udara dingin terhadap massa udara masuk dua nosel.Kata kunci: Fluent, kappa-epsilon, Ranque Hilsch Vortex Tube, simulasi numerik, tabungvorteks, vorteks aliranAbstractVortex tube known as Ranque Hilsch Vortex Tube (RHVT) is a simple device with no movingparts in it that separates the pressurized air to enter into two separate streams of air that is hotand cold air simultaneously on each output. The process of separation of the two streamswhich flow one into the cold and the heat flow can be viewed as the energy separation process.The theory of the separation process generally makes the energy obtained from the experimentand most of the numerical simulations. This paper discusses the phenomenon of separation ofcold and heat flow in the counter flow type RHVT the air into the nozzle pressure of 2 atm witha number of nozzles 2 pieces.
