Abstract
The refrigerator vortex tube is an industrial simple device that used for generating cold and hot air streams from one pressurized air source. Diverse clarifications for the phenomenon of the temperature separation were introduced last years, but till now there isn{u2019}t a clear proposal that explains this phenomenon completely. This effort is devoted to simulate the flow within the refrigerator vortex tube and explain its operating mechanism. Furthermore, this study shows the influence of cold mass fraction, air inlets number and shape and the divergence angle of the hot tube on the cooling performance to provide optimum geometrical and operational properties
