This book describes the most reliable methods for evaluating the transport properties of pure gases and fluid mixtures, such as viscosity, thermal conductivity and diffusion. The authors place particular emphasis on recent theoretical advances in our understanding of fluid transport properties in all the different regions of temperature and pressure. In addition to the important theoretical tools, the authors cover the different methods of data representation, and they follow this with a section that demonstrates the application of selected models in a range of circumstances. They then offer case studies of transport property analysis for real fluids, and the book concludes with a discussion of various international data banks and prediction packages. Advanced students of kinetic theory, as well as engineers and scientists involved with the design of process equipment or the interpretation of measurements of fluid transport properties, will find this book indispensable.
