From the experiment, its shows that conical valve shape has smallest effect on cooling performance (0.124) of the Ranque-Hilsch vortex tube. Figures and Tables. Comprehensive meticulous literature study on vortex tube is presented in our previous paper,,. Key Words: vortex tube, refrigeration, nozzle, pipes, I. Vortex tube is composed of inlet nozzles, diaphragm, cold orifice, hot control valve, hot tube, and chamber the schematic diagram of a vortex tube as given in the Figure 1(B). Compressed air is passing to the vortex tube through the nozzle (a) in the nozzle the air injected with high speed velocity and enters into the chamber. Keyword: Refrigeration Effect, Vortex tube etc. With no moving parts, a vortex tube spins compressed air to separate the air into cold and hot air streams. Moreover, Ranequ proposed this phenomenon occurring in vortex tube due to adiabatic expansion near the inlet nozzle and adiabatic compression of air near the hot control … The various explanations for the temperature separation have been examined and the different factors within these previous explanations were evaluated, and a new hypothesis was proposed.

Compressed air is passing to the vortex tube through the nozzle (a) in the nozzle the air injected with high speed velocity and enters into the chamber. hot air out one end, cold out the other. This paper presents a new type of vortex tube ice storage refrigeration technology, and the property of a vortex tube is tested and theory of the ice storage system is studied, then the ice making time and the best working state are obtained. Abstract: This paper is about experimental investigation of the orifice diameter, swirl generator and conical valve shape influence the cooling performance of Ranque-Hilsch vortex tube. A partly modified standard K-ε turbulent model has been used to investigate the flow characteristics and energy separation effect in the vortex tube. Abstract: This paper is about experimental investigation of the orifice diameter, swirl generator and conical valve shape influence the cooling performance of Ranque-Hilsch vortex tube. But due to its inefficiency the patent and idea was rejected and it was highly unpopular.

Vortex tube is composed of inlet nozzles, diaphragm, cold orifice, hot control valve, hot tube, and chamber the schematic diagram of a vortex tube as given in the Figure 1 (B). Share This Paper. Fig-1(b): CFD results for the 30 cm vortex tube model showing the rate of heat and work transfer per unit length along the control surface separating the hot and cold control volumes[1]. The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. An application of CFD model for the simulation of a strongly swirling and high speed flow in the vortex tube is presented in this paper. The device is also called Ranque-Hilsch tubes and Ranque-Hilsch vortex tubes, named after the people who discovered a tube was a French physics student named Georges Ranque in the year of 1930; several studies presented the principle of finding on the unique energy separation phenomena in the vortex tube. A semi-empirical model of the vortex tube is described based on this concept and predictions made using this model are shown to agree well with some experimental data.

The model originates from the local compression/expansion and inner friction hypothesis anticipated to be responsible for the Ranque–Hilsch effect.

Research Papers. The vortex tube is a device which uses air as refrigerating fluid since air is abundantly available in nature hence vortex tubes proves to be inexpensive and unhazardous to nature.

Ranque in 1931[1]. Also the effect of insulation on vortex tube is investigated in this paper.
