Thermohydraulic Design of Nuclear Devices 1
- Department of Nuclear Reactors
With this course, students are introduced into the problem of thermal calculation and design of nuclear devices thermodynamic diagrams. Step by step they will learn more about basic quantities and terms in technical thermodynamic, basic reversible and non-reversible thermodynamic changes and cycles with ideal gas. The main focus of course is in thermodynamic of steam: basic reversible and non-reversible thermodynamic changes with steam and Rankine-Clausius cycle. In detail are analyed miscellaneous methods of thermal efficiency increasing of Rankine-Clausius cycle. Course closure is dedicated to thermodynamic of gas mixtures and humid air.
