Thermodynamics I
3 Credits
A basic course introducing the classical theory of thermodynamics. Applications of the first law of thermodynamics are used to introduce the student to thermodynamic processes for closed and open systems. The Clausius and Kelvin-Planck statements of the second law are then correlated with the concept of entropy and enthalpy to investigate both real and reversible processes and the thermodynamic properties of pure substances. These techniques are then used to evaluate thermodynamic cycles for a variety of applications in power generation and refrigeration. Students are then introduced to techniques to improve thermal efficiency of these cycles such as reheat, regeneration, and co-generation.
