Abstract:

A vortex tube is a mechanical device for separating a stream of compressed air into two streams of colder and warmer air than the inlet stream at the same time. Simple design, small volume and no need for repair, caused this dual-purpose device to be considered in the industry. In the paper, using simulation and computational fluid dynamics technique, the effect of inlet air pressure on the performance of a vortex tube device has been investigated. To solve the flow field equations, the k-ε turbulence model is used and the model geometry is considered constant. The results show that each vortex pipe has an optimal working pressure that is both economically and economically justifiable. This working pressure was 4.8 bar in the current project. The simulation results show that for cooling purposes, using a mass ratio of 0.3 will cause a higher separation in the cold output and for heating purposes, it is recommended to use a cold mass ratio of about 0.8.
