Many practical operations, such as environment depollution, blood dialysis or product purification, require matter transfer. With an emphasis on the aforementioned subjects, this book revisits the founding principles of materials transfer on the basis of Fick’s first law, which constitutes the foundation of diffusional phenomena. Additionally, continuity equations translating the macroscopic balances of systems are established. These balances constitute Fick’s second law, which can be applied to quantify the fluxes of matter transferred in each situation, provided physical data is available. To this end, Mass Transfers and Physical Data Estimation pays particular attention to methods of data estimation. Methods presented in this book are applied to several practical cases, such as diffusion in catalytic reactions or the reconstitution of cartilage in human bone joints.

This highly recommended book on transport phenomena shows readers how to develop mathematical representations (models) of physical phenomena. The key elements in model development involve assumptions about the physics, the application of basic physical principles, the exploration of the implications of the resulting model, and the evaluation of the degree to which the model mimics reality. This book also expose readers to the wide range of technologies where their skills may be applied.

Whether in a solar thermal power plant or at the heart of a nuclear reactor, convection is an important mode of energy transfer. This mode is unique; it obeys specific rules and correlations that constitute one of the bases of equipment-sizing equations. In addition to standard aspects of convention, this book examines transfers at very high temperatures where, in order to ensure the efficient transfer of energy for industrial applications, it is becoming necessary to use particular heat carriers, such as molten salts, liquid metals or nanofluids. With modern technologies, these situations are becoming more frequent, requiring appropriate consideration in design calculations. Energy Transfers by Convection also studies the sizing of electronic heat sinks used to ensure the dissipation of heat and thus the optimal operation of circuit boards used in telecommunications, audio equipment, avionics and computers.

Inside industrial furnaces and combustion chambers, energy is essentially exchanged by radiation. It is through the same mechanism that the energy emitted by the Sun spreads through different media to reach the Earth. Developing a sound understanding of the laws underlying energy exchanges by radiation is therefore essential, not only for establishing design equations for industrial equipment, but also for an optimal harvesting of solar energy and a better understanding of climate change phenomena such as the greenhouse effect. Energy Transfers by Radiation establishes the basic laws and equations which support the quantification of energy fluxes transferred between surfaces for situations similar to those usually encountered in industrial processes or in solar energy applications.

While the topic of heat and mass transfer is an old subject, the way the book introduces the concepts, linking them strongly to the real world and to the present concerns, is particular. The scope of the different developments keeps in mind a practical energy engineering view.

Heat Transfer 2 deals with radiation, heat exchangers and flat plate solar collectors. It presents the treatment of radiation in semi-transparent media to be taken into account for insulation or recovery of high temperature waste heat (energy saving in industry), as well as in certain solar applications (energy transition). The numerous solved exercises allow the reader to grasp the whole range of applications, whether in the field of building, transport, materials or the environment. The appendices contain all the data needed to solve the exercises and will be a valuable source of information. This book is designed for masters and engineering students who are interested in all aspects of heat transfer, but also for engineers who will find the bases needed to understand similar phenomena (conduction-convection-radiation), but which require a different form of reflection and approach.
