Book Description
The development of engine waste heat recovery (WHR) technologies attracts ever increasing interests due to the rising strict policy requirements and environmental concerns. Organic Rankine Cycle (ORC) can convert low medium grade heat into electrical or mechanical power and has been widely recognized as the most promising heat-driven technologies. A typical internal combustion engine (ICE) converts around 30% of the overall fuel energy into effective mechanical power and the rest of fuel energy is dumped through the engine exhaust system and cooling system. Integrating a well-designed ORC system to ICE can effectively improve the overall energy efficiency and reduce emissions with around 2-5 years payback period through fuel saving. This book chapter is meant to provide an overview of the technical development and application of ORC technology to recover wasted thermal energy from the ICE with a particular focus on vehicle applications.

Book Description
Power conversion systems based on organic Rankine cycles have been identified as a potential technology especially in converting low-grade waste heat into electricity as well as in small-scale biomass, solar, or geothermal power plants. The theoretical analysis can guide the ORC design, but cannot predict accurately the system performance. Actually, the operation characteristics of every component have a vital effect on the system performance. This chapter presents the detailed operation characteristic of a small-scale ORC. The effects of the operation parameters, the mixture working fluid and the operation strategy on system overall performance are addressed. It can be concluded that improving the system overall performance should give priority to increase the pressure drop. Whether the mixtures exhibit better thermodynamic performance than the pure working fluids depend on the operation parameters and mass fraction of mixtures. The mixture working fluids obtain a higher expander shaft power but a relatively higher BWR. The expander rotating speed for standalone operation strategy keeps rising from 2320 to 2983 rpm, whereas that of grid connect operation strategy keeps constant of 3600 rpm.

Book Description
This book covers the fundamentals of thermodynamics required to understand electrical power generation systems, honing in on the application of these principles to nuclear reactor power systems. It includes all the necessary information regarding the fundamental laws to gain a complete understanding and apply them specifically to the challenges of operating nuclear plants. Beginning with definitions of thermodynamic variables such as temperature, pressure and specific volume, the book then explains the laws in detail, focusing on pivotal concepts such as enthalpy and entropy, irreversibility, availability, and Maxwell relations. Specific applications of the fundamentals to Brayton and Rankine cycles for power generation are considered in-depth, in support of the book’s core goal- providing an examination of how the thermodynamic principles are applied to the design, operation and safety analysis of current and projected reactor systems. Detailed appendices cover metric and English system units and conversions, detailed steam and gas tables, heat transfer properties, and nuclear reactor system descriptions.

Book Description
Concerns for fuel economy and reduced emissions have turned the attention of automotive internal combustion engine manufacturers to the exhaust system and towards technological system development to account for the significant levels of potential energy that can be recovered. The present volume on Automotive Exhaust Emissions and Energy Recovery for both gasoline and diesel engines is therefore both timely and appropriate. Whereas diesel engines have been predominantly turbocharged, only a relatively small percentage of gasoline engines are similarly equipped, which has led to significant efforts by engine manufacturers in recent years to downsize and down-speed these engines. On the other hand, the relative focus in diesel engine development in terms of emissions and exhaust energy recovery has shifted toward devices other than the turbocharger for enhanced energy recovery and emissions control technologies in order to allow the diesel engines of the future to keep up with the dual-demand for very low emissions and increasing levels of fuel economy. The book focuses on the exhaust system and the technologies and methods used to reduce emissions and increase fuel economy by capitalising on the exhaust gas energy availability (either in the form of gas kinetic energy or as waste heat extracted from the exhaust gas). It is projected that in the short to medium term, advances in exhaust emissions and energy recovery technologies will lead the way in internal combustion engine development and pave the way towards increasing levels of engine hybridisation until fully electric vehicle technology can claim a level of maturity and corresponding market shares to turn the bulk of this focus away from the internal combustion engine. This book is aimed at engine research professionals in the industry and academia, but also towards students of powertrain engineering. The collection of articles in this book reviews the fundamentals of relevance, recent exhaust system technologies, details recent or on-going projects and uncovers future research directions and potentials.
