Overview
This three hour online course explores the thermodynamic aspects of cogeneration (generation of electric power and utilizing the waste heat for thermal energy needs). It briefly explains basic thermodynamic concepts in terms that mechanical engineers can grasp, and provides a refresher for those who have not worked with heat engine cycles for a while. Carnot and Rankine cycles are described. The importance of understanding the Second Law of Thermodynamics and applying Second Law analyses to newly developing energy concepts are stressed. Of particular interest is the use (and misuse) of the term “thermal efficiency” when discussing cogeneration cycles. The different “grades” of energy are discussed and the relative values of electrical energy, thermal and mechanical work.
The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
