EBOOK - Heat Transfer - A Practical Approach 2nd Edition (Yunus A. Cengel)


EBOOK - Truyền nhiệt - Phương pháp tiếp cận thực tế (Yunus A. Cengel) - 874 Trang.

Heat transfer is a basic science that deals with the rate of transfer of thermal energy. This introductory text is intended for use in a first course in heat transfer for undergraduate engineering students, and as a reference book for practicing engineers. The objectives of this text are:


- To cover the basic principlesof heat transfer.
- To present a wealth of real-world engineering applicationsto give students a feel for engineering practice.
- To develop an intuitive understandingof the subject matter by emphasizing the physics and physical arguments.

Students are assumed to have completed their basic physics and calculus sequence. The completion of first courses in thermodynamics, fluid mechanics, and differential equations prior to taking heat transfer is desirable. The relevant concepts from these topics are introduced and reviewed as needed.
