Experimental Evaluation of the Energy Performance of an Air Vortex Tube when the Inlet Parameters are Varied

摘要

he paper presentsthe analysis of theenergy performanceof an airvortexcooling tube under variations of theair inlet properties, with three independent experimental tests validated through the energy balance in the device.The experimental analysis includes the following variations of the input conditions: First, the effectof the air inletpressure to the vortex tube, focused on the analysis of temperature variations in the output cold stream and in the coolingcapacity when the cold flow fraction varies. Second, we studied air inlet temperature variations to the vortex tube underdifferent cold flow fractions, which is an analysis not found in the literature. And finally, is studied the performance of thevortex tube when the insulation is provided or in absence of insulation.
