        Recently, the Ranque-Hilsch vortex tube is widely used for the local cooler of industrial equipment for special purpose. Although many studies on energy extraction in the vortex tube using air as the working fluid have been made so far, a few experimental studies treated solid particles extraction for incompressible fluid. So, an experimental study for the solid particles extraction in the vortex tube(Ranque-Hilsch vortex tube) using the water which is essentially an incompressible fluid is presented. The experiments were carried out with various cold end orifice diameter ratios ranging from 0.25 to 0.70, the input pressure ranging from 1 to 3MPa was considered. The emphasis was given to examine the effect of geometry factors of vortex tube at working fluid(water) for solid particles(Al2O3) extraction. The optimum geometry factor and inlet pressure for the maximum solid particles extraction was found that the smaller cold end orifice diameter ratio and the higher inlet pressure in experimental condition increase.
