Opis

Ranque-Hilsch vortex tube (RHVT) is an equipment that sequestrated a single stream flow of fluid (gas) into two different flows simultaneously, one hotter than the inlet and one cooler. Traditionally vortex tubes are mostly operated at high entrance pressures (10 psig) and always used for cooling operations. There are semi-industrial and industrial usages which can lead to unused pressurized gases. Vortex tube energy separation can be used as a waste pressure energy recovery method from high and low pressure references (sources). In various industrial systems, magnitudes of waste pressure may be lower but may have significant mass flow rates. Hence it is important to make sure that vortex tube provides the required energy separation while harnessing the low pressure but high mass flow rate waste energy and utilizes it for not only cooling but also for heating purposes. Our recent experimental observations show that in the low inlet pressure regime (
