Advanced Computational Methods And Experiments In Heat Transfer Xii

Containing papers presented at the twelfth in a series of successful international conferences on Advanced Computational Methods and Experiments in Heat Transfer, this book covers the latest developments in this important field. Heat Transfer plays a major role in emerging application fields such as sustainable development and the reduction of greenhouse gases, as well as micro- and nano-scale structures and bio-engineering. Typical applications include heat exchangers, gas turbine cooling, turbulent combustion and fires, electronics cooling, melting and solidification. The nature of heat transfer problems is complex, involving many different simultaneously occurring mechanisms (e.g., heat conduction, convection, turbulence, thermal radiation. phase change). Their complexity makes it imperative that we develop reliable and accurate computational methods to replace or complement expensive and time-consuming experimental trial and error work. Tremendous advances have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and more powerful computers capable of performing efficient and rapid calculations. Nevertheless, to further progress, it will also be necessary to develop theoretical and predictive computational procedures--both basic and innovative--and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. The book includes such topics as: Heat Transfer in Energy Producing Devices; Heat Transfer Enhancement; Heat Transfer Problems; Natural and Forced Convection and Radiation; Multiphase Flow Heat Transfer; Modelling and Experiments.

In engineering design and development, reliable and accurate computational methods are requested to replace or complement expensive and time consuming experimental trial and error work. Tremendous advancements have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and computer developments to achieve efficient and rapid calculations. Nevertheless, to further progress in computational methods will require developments in theoretical and predictive procedures – both basic and innovative – and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. This book contains the edited versions of the papers presented at the Tenth International Conference on Advanced Computational Methods and Experimental Measurements in Heat Transfer and Mass Transfer held in Maribor, Slovenia in July 2008. The objective of this conference series is to provide a forum for presentation and discussion of advanced topics, new approaches and application of advanced computational methods and experimental measurements to heat and mass transfer problems. The contributed papers are grouped in the following appropriate sections to provide better access for readers: Natural and forced convection; Heat exchangers; Advances in computational methods; Heat recovery; Heat transfer; Modelling and experiments.

Heat Transfer topics are commonly of a very complex nature. Often different mechanisms like heat conduction, convection, thermal radiation, and non-linear phenomena, such as temperature-dependent thermophysical properties, and phase changes occur simultaneously. New developments in numerical solution methods of partial differential equations and access to high-speed, efficient and cheap computers have led to dramatic advances during recent years. This book publishes papers from the Ninth International Conference on Advanced Computational Methods and Experimental Measurements in Heat and Mass Transfer, exploring new approaches to the numerical solutions of heat and mass transfer problems and their experimental measurement. Papers encompass a number of topics such as: Diffusion and Convection; Conduction; Natural and Forced Convection; Heat and Mass Transfer Interaction; Casting, Welding, Forging and other Processes; Heat Exchanges; Atmospheric Studies; Advances in Computational Methods; Modelling and Experiments; Micro and Nano Scale Heat and Mass Transfer; Energy Systems; Energy Balance Studies; Thermal Material Characterization; Applications in Biology; Applications in Ecological Buildings; Case Studies.

Presenting the basic mechanisms for transfer of heat, this book gives a deeper and more comprehensive view than existing titles on the subject. Derivation and presentation of analytical and empirical methods are provided for calculation of heat transfer rates and temperature fields as well as pressure drop. The book covers thermal conduction, forced and natural laminar and turbulent convective heat transfer, thermal radiation including participating media, condensation, evaporation and heat exchangers. This book is aimed to be used in both undergraduate and graduate courses in heat transfer and thermal engineering. It can successfully be used in R & D work and thermal engineering design in industry and by consultancy firms

Starting in Portsmouth in 1988, Heat Transfer XIV: Simulation and Experiments in Heat Transfer and its Applications contains the proceedings of the fourteenth conference in the well-established series on Simulation and Experiments in Heat Transfer and its applications. Heat Transfer might be considered as an established and mature scientific discipline, but it has played a major role in new emerging areas such as sustainable development and reduction of greenhouse gases as well as for micro- and nano- scale structures and bioengineering. Tremendous advances have been achieved during recent years due to improved numerical solution methods for non-linear partial differential equations, turbulence modelling advancements and developments of computers and computing algorithms to achieve efficient and rapid simulations. The papers contained in this book present studies on advanced topics, new approaches and applications of innovative advanced computational methods and experimental measurements to heat and mass transfer problems. Further progress in computational methods requires developments in theoretical and predictive procedures and in applied research. The following list covers some of the topics presented: Energy conversion devices; Heat transfer enhancements; Heat exchanges; Natural and forced convection; Radiation; Multiphase flow heat transfer; Modelling and simulation; Heat recovery; Heat and mass transfer problems; Heat transfer in nature; Renewable energy systems; Biotechnology; Thermal electric devices and High temperature heat transfer.
