Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a gas into hot and cold streams. It has no moving parts. The gas is injected tangentially into a chamber with high degree of swirl. At the other end because of the nozzle only the outer periphery part is allowed to escape where as the inner part is forced into the inner vortex with a small diameter within the outer vortex. A two dimensional computational model was used to determine the energy separation and flow phenomenon. An axisymmetric model for a counter flow vortex tube was used. The model on simulation explains the temperature separation phenomena within the vortex tube. The fluid in the vortex tube has three regions. One is the fluid entering at a particular temperature and pressure which leads into two outlets, the cold exit and the hot exit where the temperature is less or more from the inlet temperature respectively. The swirl flow results in the temperature drop at the cold exit. The temperature separation occurs because of the heat transfer from the central flow to the peripheral flow. The simulation is done with fluent using the k-e model. FLUENT is software used to simulate fluid flow problems. FLUENT is generally used for computational Fluid Dynamics problems. It uses the finite-volume method to solve the governing equations for a fluid. It provides a wide field to solve problems. Geometry and grid generation is done using GAMBIT.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the state of the art of numerical simulation of transitional and turbulent flows and provides an active forum for discussion of recent developments in simulation techniques and understanding of flow physics. Following the tradition of earlier DLES workshops, these papers address numerous theoretical and physical aspects of transitional and turbulent flows. At an applied level it contributes to the solution of problems related to energy production, transportation, magneto-hydrodynamics and the environment. A special session is devoted to quality issues of LES. The ninth Workshop on 'Direct and Large-Eddy Simulation' (DLES-9) was held in Dresden, April 3-5, 2013, organized by the Institute of Fluid Mechanics at Technische Universität Dresden. This book is of interest to scientists and engineers, both at an early level in their career and at more senior levels.

This book was released on 1961 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book Computational Methods in Multiphase Flow VIII written by P. Vorobieff and published by WIT Press. This book was released on 2015-04-20 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest research in one of the most challenging, yet most universally applicable areas of technology. Multiphase flows are found in all areas of technology, at all length scales and flow regimes, involving compressible or incompressible linear or nonlinear fluids. The range of related problems of interest is vast, including astrophysics, biology, geophysics, atmospheric process, and many areas of engineering. The solution of the equations that describe such complex problems often requires a combination of advanced computational and experimental methods. For example, any models developed must be validated through the application of expensive and difficult experimental techniques. Numerous problems in the area thus remain as yet unsolved, including modelling nonlinear fluids, modelling and tracking interfaces, dealing with multiple length scales, characterising phase structures, and treating drop break-up and coalescence. The papers contained in the book were presented at the eighth in a well established series of biennial conferences that began in 2001. They represent close interaction between numerical modellers and other researchers working to gradually resolve the many outstanding issues in understanding of multiphase flow. The papers in the book cover such topics as: Multiphase Flow Simulation; Bubble and Drop Dynamics; Interface Behaviour; Experimental Measurements; Energy Applications; Compressible Flows; Flow in Porous Media; Turbulent Flow; Image Processing; Heat Transfer; Atomization; Hydromagnetics; Plasma; Fluidised Beds; Cavitation.

This book was released on 1989 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: A translation of the 1984 Russian work. Nonequlibrium condensation is an important aspect of weather forecasting, aerosol formation, and the design of jet propulsion engines, steam turbines and nuclear reactors. It has recently taken on a new significance with the development of technologies such as the production of fine powders, cluster spraying, the development of laser media and isotope separation. This volume presents the general theory of condensation in high-speed gas flows, and the new theoretical, experimental and numerical methods necessary for solving the partial differential equations governing the flows.

Download or read book Void Fraction Pressure Drop and Heat Transfer in High Pressure Condensing Flows Through Microchannels written by Brendon Louis Keinath and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow mechanisms affect transport processes during condensation. Most studies on two-phase flow regimes are qualitative in nature, typically providing only information to guide the identification of the respective regimes and the transitions between them. These studies have, however, not yielded quantitative information to assist the development of pressure drop and heat transfer models. Such qualitative studies have also yielded results with considerable variability between investigators. A comprehensive investigation of flow mechanisms, void fraction, pressure drop and heat transfer during condensation of R404A in microchannels was conducted. In contrast to all prior investigations, high-speed video recordings and image analyses were used to directly measure void fraction, slug frequencies, vapor bubble velocity, vapor bubble dimensions and liquid film thicknesses in tube diameters ranging from 0.508 to 3.00 mm. Experiments were conducted at reduced pressures and mass fluxes ranging from 0.38 to 0.77 and 200 to 800 kg m-2 s-1, respectively, to document their influences on the condensation process at local vapor qualities ranging from 0 to 1. This information was used to develop a model for the void fraction in condensing flows. A complementing set of heat transfer and pressure drop measurements were conducted on the same geometries at similar conditions, and the void fraction model was used in conjunction with these measurements to develop improved heat transfer and pressure drop models. This comprehensive set of experiments and analyses yields a self-consistent and accurate treatment of high-pressure condensation in small hydraulic diameter geometries. Furthermore, the heat transfer model was found to agree well with condensing ammonia and carbon dioxide data that were obtained at significantly different conditions in different tube diameters. The added physical understanding of the condensation process and the models developed will serve as important building blocks for the design of microscale condensers and thermal systems.
