The Comparision of Heating and Cooling Performance of a Serial and Parallel Connected Counter Flow Ranque–Hilsch Vortex Tube
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2017, Vol 5, Issue 4
Abstract
In this study, two counter flow Ranque-Hilsch Vortex Tubes with body length 100 mm and inlet diameter 7 mm were used having no moving parts except a control valve for adjustment of volume flow rates. Six-orifice nozzles were used which are made of polyamid plastic, aluminum and brass in the two vortex tubes connected with each other serial and parallel. Heating and cooling performance of vortex tubes were compared experimentally by using compressed air as a working fluid in RHVT with pressure values from 200 kPa to 600 kPa with 50 kPa variation. Minimum cold fluid and maximum hot fluid temperatures were both determined for parallel connection setup. The minimum cold fluid temperature was obtained at 600 kPa inlet pressure with aluminum nozzle material as -19.6 0C while the maximum hot fluid temperature was obtained at 600 kPa inlet pressure with brass material as 41.6 0C.
