Описание

Второе издание хорошо известной и имеющей огромную ценность книги было полностью пересмотрено и переработано. Издание основано на личном опыте автора, в дополнение к информации из оригинального издания за период прошлых лет, начиная с его первой публикации в 1990-е годы.

В данной книге обсуждаются практические шаги, которые могут быть предприняты для снижения негативных последствий нестационарных потоков, которым в некоторой степени подвергаются все трубопроводные системы. Здесь также обсуждаются причины возникновения нестационарных потоков и специальные средства для анализа явлений, чтобы определить потенциальное влияние потоков и разработать стратегии управления ими.

Данная книга предназначена для инженеров-конструкторов перерабатывающих отраслей промышленности и, в особенности, для специалистов - практиков, вовлечённых в процесс конструирования и обеспечения безопасности и надёжности трубопроводных систем. Здесь содержится важная информация для студентов старших курсов и выпускников инженерно-технических факультетов, интересующихся особенностями нестационарных потоков.

Совместная публикация издательств Professional Engineering Publishing, UK, и ASME Press.

This second edition of a well-established and highly regarded volume has been comprehensively revised and updated. It is based on the author's personal experience, in addition to feedback from the original edition in the years since its initial publication in the 1990s.
This book discusses practical steps that can be taken to alleviate the negative consequences of transient flows, which are experienced at some point by all pipeline systems.  The causes of transient flows are also discussed, as well as tools for analyzing events to determine the potential impact of the flows and to develop strategies for controlling them.
This book is intended for design engineers in the process industries, and in particular those practitioners responsible for designing pipeline systems and maintaining their safety and reliability. This text also offers invaluable information for senior and graduate level engineering students with an interest in fluid transient phenomena.
