Описание: Turbomachinery is a challenging and diverse field, with applications for professionals and students in many subsets of the mechanical engineering discipline, including fluid mechanics, combustion and heat transfer, dynamics and vibrations, as well as structural mechanics and materials engineering. Originally published more than 40 years ago, Fluid Mechanics and Thermodynamics of Turbomachinery is the leading turbomachinery textbook. Used as a core text in senior undergraduate and graduate level courses this book will also appeal to professional engineers in the aerospace, global power, oil & gas and other industries who are involved in the design and operation of turbomachines. For this new edition, author S. Larry Dixon is joined by Cesare Hall from the University of Cambridge, whose diverse background of teaching, research and work experience in the area of turbomachines is well suited to the task of reorganizing and updating this classic text.

Турбомашиностроение - сложная и разнообразная область, которая может быть использована профессионалами и студентами во многих областях машиностроения, включая механику жидкости и газа, горение и теплопередачу, динамику и вибрации, а также строительную механику и материаловедение. Впервые опубликованный более 40 лет назад, "Механика жидкости и термодинамика турбомашин" является ведущим учебником по турбомашиностроению. Эта книга, используемая в качестве основного учебного пособия на старших курсах бакалавриата и магистратуры, также будет интересна профессиональным инженерам аэрокосмической, энергетической, нефтегазовой и других отраслей промышленности, которые занимаются проектированием и эксплуатацией турбомашин. Над этим новым изданием к автору С. Ларри Диксону присоединился Чезаре Холл из Кембриджского университета, чей обширный опыт преподавания, исследований и работы в области турбомашин хорошо подходит для решения задачи реорганизации и обновления этого классического текста.
