Ranque-Hilsh vortex tube
Obrlík, Jan ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
Ranque-Hilsch vortex tube is thermally-fluid device in which there is a conversion of the pressure energy of the incoming fluid stream to heat energy of two exiting streams without any mechanical parts. The first part of this paper deal with the basic distribution, applications and principle of the vortex tube, which is not fully understood. In the second part there has been carried out a search about performed experimental measurements. Based on this research is designed optimized experiment. The last part of work is the evaluation of the measurement, which was carried out on an industrial vortex tube.

Vortex tube made by additive technology
Spáčil, Petr ; Šnajdárek, Ladislav (referee) ; Chýlek, Radomír (advisor)
The aim of this bachelor's thesis is designing and 3D printing of a detachable Ranque-Hilsch vortex tube. In the following chapters will be presented basic types of vortex tubes and its usage. Then the thesis deals with parameters, that have an impact on the effectiveness of vortex tube. In the main part, the design of individual parts is described. After 3D printing and assembling, the vortex tube's performance is measured with variations of some parameters.

Vortex tube
Chýlek, Radomír ; Škorpík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The purpose of this diploma thesis was to find optimal operational parameters of Ranque–Hilsch vortex tube that would give the best results of temperature separation, and to create a numerical model of the device. Firstly, extensive research of current literature was done and analytical model of the tube was created. Then, the numerical model of the vortex tube was designed using Star-CCM+ software. Afterward, best fitting turbulence model was chosen to do the calculation and optimal geometrical parameters of the tube were obtained as a result of CFD simulation. Then, inlet nozzles for the tube were designed and manufactured. Experimental evaluation of the vortex tube and description of its optimal settings form a substantial part of the project. Finally, the data obtained from the experiment were compared to the results of numerical analysis and conclusions were deduced.
