Transient Heat Transfer in a Rotating Cylindrical Cavity


Book Description

This thesis describes an experimental study of the transient heat transfer from both a free disc and a rotating cavity. Measured disc surface temperatures - from heating, cooling and quasi-steady tests - were used as boundary conditions for the solution of Fourier's conduction equation. The local and average Nusselt numbers were obtained from the computed temperature distribution, inside the disc, at each time-step.



















Handbook of Thermal Science and Engineering


Book Description

This Handbook provides researchers, faculty, design engineers in industrial R&D, and practicing engineers in the field concise treatments of advanced and more-recently established topics in thermal science and engineering, with an important emphasis on micro- and nanosystems, not covered in earlier references on applied thermal science, heat transfer or relevant aspects of mechanical/chemical engineering. Major sections address new developments in heat transfer, transport phenomena, single- and multiphase flows with energy transfer, thermal-bioengineering, thermal radiation, combined mode heat transfer, coupled heat and mass transfer, and energy systems. Energy transport at the macro-scale and micro/nano-scales is also included. The internationally recognized team of authors adopt a consistent and systematic approach and writing style, including ample cross reference among topics, offering readers a user-friendly knowledgebase greater than the sum of its parts, perfect for frequent consultation. The Handbook of Thermal Science and Engineering is ideal for academic and professional readers in the traditional and emerging areas of mechanical engineering, chemical engineering, aerospace engineering, bioengineering, electronics fabrication, energy, and manufacturing concerned with the influence thermal phenomena.




Heat Transfer in a Cylindrical Rotating Cavity


Book Description

In this thesis are presented the results of an investigation of the flow and heat transfer inside a heated rotating cylindrical cavity, which forms a simple model for the space between corotating compressor or turbine discs in a gas turbine. Although the study was mainly experimental, the Reynolds analogy has been used to obtain semi-empirical correlations for the heat transfer for the linear turbulent Ekman layers in a cavity with a radial outflow.




Flow and Heat Transfer in Rotating-disc Systems


Book Description

This volume is devoted to the flow and heat transfer between co-rotating discs, and unifies the subject by means of physical insight and mathematical models, validated using experimental data. Many phenomena, unique to rotating flows, are explained, and empirical correlations and theoretical methods, suitable for design purposes, are presented. Data is provided within the book for validating CFD codes which are being increasingly used to compute the flow in rotating-disc systems. Since the publication of Volume 1 in 1989, there has been an increasing interest in rotating disc systems, mainly from research workers and engine designers concerned with understanding and computing the complex flow and heat transfer that occur inside the internal cooling-systems of gas-turbine engines. This book should be of interest to them as it may assist them in making more efficient use of cooling air systems, resulting in both economic and environmental benefits.
