This book is the second of two follow-on volumes to the author's bestseller, Principles of Combustion, Second Edition published in 2005. This text focuses on applications, with coverage not available elsewhere, including solid propellants, burning behavior, and chemical boundary layer flows. Kuo provides a multiphase systems approach beginning with more common topics and moving to higher level applications. As with Kuo's earlier book, large numbers of examples and problems and a solutions manual are provided.
