Thermodynamic Cycles: Efficiency and Optimization

This lecture delves into the principles of thermodynamic cycles, focusing on the Rankine cycle as a major method for electricity production. The instructor explains the conversion of heat into mechanical power, the importance of heat engines in industrial development, and the thermodynamic properties of fluids. The lecture covers the Carnot factor, the efficiency of turbines, and the strategies to enhance cycle efficiency, such as increasing pressure, reheating, and steam extraction. Different types of cycles, including supercritical and wet cycles, are discussed, along with the challenges of working with low-temperature heat sources. The instructor also explores the use of mixtures and refrigerants in cycles to optimize efficiency and mechanical power production.
