Thermodynamics
Course Recap
- Different primary energy forms (chemical, nuclear, solar, kinetic) need to be converted into useful energy (mechanical, electrical).
- Applications are engines, aircraft/rocket propulsions, wind turbines, fuel cells, steam and gas turbines, combustion, compressors, pumps
- Thermodynamics provides us with tools for design, performance assessment, improvements and optimization.
- Thermal efficiency:
-
\eta_{thermal} = \frac{Useful work/energy}{energy provided} - Combustion: gasoline ~35%, diesel ~42%
- fossil power production: ~35-48%
- solar thermal power production: ~18-22%

Laws of Thermodynamics
[!important] 0th law: Equilibrium If two systems are both in thermal equilibrium with a third system, then they are in equilibrium with each other.
This law establishes the concept of temperature, which is a fundamental and measurable prop
