Lecture
This lecture introduces the concept of exergy as a thermodynamic value equivalent to the cost of flows in a system, emphasizing the importance of understanding energy and mass flows, heat, and electricity exchanges. The instructor explains the first and second laws of thermodynamics, the calculation of maximum work production, exergy losses, and exergy efficiency. Through examples, the lecture illustrates how exergy analysis can identify inefficiencies in energy conversion processes and guide improvements for better system performance.
