Book Description
Efficient heat transfer technologies are essential for magnetically confined fusionreactors; this applies to both the current generation of experimental reactors as well asfuture power plants. A number of High Heat Flux devices have therefore been developedspecifically for this application. One of the most promising candidates is theHyperVapotron, a water cooled device which relies on internal fins and boiling heattransfer to maximise the heat transfer capability. Over the past 30 years, numerous variations of the HyperVapotron have been built andtested at fusion research centres around the globe resulting in devices that can nowsustain heat fluxes in the region of 20? 30MW/m2 in steady state. Unfortunately, therehave been few attempts to model or understand the internal heat transfer mechanismsresponsible for this exceptional performance with the result that design improvements aretraditionally sought experimentally which is both inefficient and costly. This thesis seeks to develop an engineering model of the HyperVapotron device usingcommercial Computational Fluid Dynamics software. To establish the most appropriatemodelling choices, in-depth studies were performed examining the turbulence models(within the Reynolds Averaged Navier Stokes framework), near wall methods, gridresolution and boiling submodels. Validation of the models is accomplished via comparison with experimental results aswell as high order Implicit Large Eddy Simulation methods. It is shown that single phasecavity flows and their related heat transfer characteristics (time-averaged) can beaccurately captured if the SST k-omega turbulence model is employed using a fine nearwallgrid throughout the cavity (e.g. y+

ISBN: 1317396294
Category : Technology & Engineering
Languages : en
Pages : 5514
Book Description
The NAB Engineering Handbook is the definitive resource for broadcast engineers. It provides in-depth information about each aspect of the broadcast chain from audio and video contribution through an entire broadcast facility all the way to the antenna. New topics include Ultra High Definition Television, Internet Radio Interfacing and Streaming, ATSC 3.0, Digital Audio Compression Techniques, Digital Television Audio Loudness Management, and Video Format and Standards Conversion. Important updates have been made to incumbent topics such as AM, Shortwave, FM and Television Transmitting Systems, Studio Lighting, Cameras, and Principles of Acoustics. The big-picture, comprehensive nature of the NAB Engineering Handbook will appeal to all broadcast engineers—everyone from broadcast chief engineers, who need expanded knowledge of all the specialized areas they encounter in the field, to technologists in specialized fields like IT and RF who are interested in learning about unfamiliar topics. Chapters are written to be accessible and easy to understand by all levels of engineers and technicians. A wide range of related topics that engineers and technical managers need to understand are covered, including broadcast documentation, FCC practices, technical standards, security, safety, disaster planning, facility planning, project management, and engineering management.
