E-mail: m.kargaran@ ABSTRACT Vortex tube is a device which is capable of separating hot and cold gas stream form an inlet gas stream with a proper pressure .Separating cold and hot streams by using vortex tube can be used in industrial applications such as cooling equipment and refrigerators . This device suits for these applications because its light ,simple and more importantly it is compact . Many researches have been carried out in order to identify the factor which affects Vortex tube performance .Here ,an experimental study has been conducted to determine the effect of geometrical parameters on vortex tube performance and air also used as a working fluid .To achieve the maximum proficiency of a vortex tube ,form the data which obtained experimentally , optimum values for cold orifice diameter to the VT inlet diameter (d / D) and the length of VT to its inlet diameter (L/ D) for this experiment proposed. KEYWORDS Vortex tube, geometrical parameters, orifice diameter ,tube length, Experimentation, 1. INTRODUCTION The vortex tube is a device with no moving part with the capability of splitting hot and cold gas stream from a higher pressure inlet gas. Such a phenomenon (splitting of the flow into regions of low and high total tempera
