Motivation: the distribution of flow between hot and cold sides is controlled by a tapered valve on the hot side and a orifice on the cold side and little is know about their individual roles in flow and energy separation

Approach: Several generators were made with different outlet orifice diameters and explored the interdependence of inlet pressure, cold fraction and orifice diameter with the performance of the vortex tube.

Fundamental Issues: If the ratio of flow is maintained, what happens to the energy separation as the diameter of the generator changes size?
