Introduction to Engineering Thermodynamics

A modern open textbook covering closed and open systems, ideal gases, liquids and vapors, entropy, and steam and air power cycles. It includes 59 step by step worked examples and 96 problems with full solutions, which is exactly what most engineering students are after.

Olivier Cleynen

A dense topic by topic summary of a university engineering thermodynamics course, from energy and work through exergy and gas power cycles. Useful as a revision map when you need one specific relation fast.

Michael C. McGoodwin

Course notes for a mechanical engineering degree, organized by unit: basic concepts, the first and second laws, entropy and availability, and pure substance properties. It follows a standard syllabus, so it maps neatly onto most curricula.
