Book Description
A new explanation of the vortex tube is presented. The proposed model leads to an equivalent unsteady-flow analysis for the development of the flow in the vortex tube. Using this analysis, radial distributions of velocity and temperature can now be calculated at successive axial positions in the tube. The qualitative similarity in the development of the calculated and experimental sets of profiles with axial position is considered especially significant. A theory of vortex tube performance based upon an idealized three-dimensional flow pattern for the vortex tube is derived. Some experiments relating the idealized vortex tube analyzed to previous vortex tube measurements are described. (Author).

Book Description
The report discusses the transfer of energy between fluid elements due to viscous work and to heat conduction within (but not across) the fluid boundaries. The particular class of problems studied are unsteady, two-dimensional flows with circular streamlines. The work was originally motivated by a desire to understand the temperature separation phenomenon exhibited by the Ranque-Hilsch vortex tube. The investigation is divided into three parts. In Part I the energy field is an infinite fluid associated with the decay of what will be defined as a line impulse of angular momentum is considered. The flows of both a liquid and of a gas in the limit of Mach number equal to zero are studied, and solutions, in closed form, are obtained and compared. In Part II the corresponding flows in a cylinder of finite radius are considered. In these cases it is necessary to resort to numerical integration to obtain the desired solutions of the energy equation. In Part III a new model for the flow in a vortex tube is proposed. Using the methods developed in Part II, velocity and energy profiles are calculated and compared with previously published measurements. Some new experimental work based upon the proposed flow model is also presented. (Author).

Book Description
The book describes the thermodynamics, fluid dynamics, and working principle of the Ranque Hilsch Vortex Tube. Although vortex tubes have been around for a long time, different explications of their fundamental physics and operation can be found in literature and on the internet. This volume investigates the working principle based on thermodynamics and fluid dynamics. It provides full explication of these parameters in one single work along with results of new investigations not published elsewhere. In addition, the book features a wealth of illustrations on various aspects of the vortex tube that make it easy to read and understand.
