插图。这些支持性的图纸有助于理解理论，并且质量很好。这本书首先介绍了质量、动量和能量守恒的原理。这些带有必要假设的定律后来被用来分析一维和二维空间中的典型流动，以使人们能够彻底理解材料。派生是清楚的，并适当地进行了讨论。前七章致力于这一主题的基本方面。它们包含了对等熵流动的分析，其中包括通过变截面管道的等熵流动的单独讨论，以及正常激波、膨胀激波和斜激波的定义。接下来的章节有更多的适用性，涵盖了喷嘴的特性和具有摩擦和换热效应的流动。由于这些主题在其他专门介绍可压缩流体力学的书籍中常常被忽略，因此收录这些主题进一步加强了对主题的理解。这本书还成功地为更高级的高超声速、高温和低密度流动问题奠定了基础。所有章节后面都有工作示例和要解决的问题列表，这在演示概念的实际实施方面非常有用。这本书的附录包含了额外的实用材料，包括用作可压缩流动可视化技术的光学方法的描述，以及一些重要的表格、常量、换算因子和图表，以使读者能够轻松地理解主题。这本书是全面和良好的介绍，将吸引本科生以及研究生水平的机械和航空航天专业的学生。对于从事可压缩流动应用的资深工程师来说，它也可能是有用的。这本书得到了用于可压缩流动计算的数字代码COMPROP2的支持，该代码是免费提供的，并在书中进行了描述。它还包括该领域其他书籍的参考书目，以及与可压缩流有关的NASA有趣报告的精选。A·F·诺瓦科夫斯基博士，谢菲尔德MIMECE大学Ceng
illustrated. The supportive drawings facilitate understanding of the theory and are of good quality. The book starts with the introduction of the principles of conservation of mass, momentum and energy. These laws with the necessary assumptions are later used in analysing typical flows in one and two space dimensions to enable a thorough understanding of the material. The derivations are clear and properly discussed. The first seven chapters are dedicated to the fundamental aspects of the subject. They contain the analysis of isentropic flows with a separately discussed isentropic flow through a variable-area duct, the definition of normal, expansion and oblique shock waves. The following chapters have more applicable character and cover nozzle characteristics and flows with friction and heat exchange effects. As these topics are often neglected in other books dedicated to the compressible fluid mechanics their inclusion further enhances the understanding of the subject matter. The book also successfully attempts to lay the foundations for more advanced problems of hypersonic, high-temperature and low density flows. All the chapters are followed by worked examples and a list of problems to solve, which are extremely useful in demonstrating the practical implementation of the concepts. The book has appendices containing an additional practical material including the description of the optical methods used as compressible flow visualisation techniques as well as a selection of important tables, constants, conversion factors and diagrams to enable the readers to comprehend the subject with ease. The book is comprehensive and wellpresented and will appeal to the undergraduate as well as the graduate level mechanical and aerospace students. It could also be useful for practising engineers engaged in compressible-flow applications. The book is supported by a numerical code COMPROP2 for compressible flow computations, which is available, free of charge and described in the book. It also includes bibliographical references to other books in the field and to a selection of interesting NASA reports concerned with compressible flow. Dr A. F.
