Exploring Thermodynamics with Ansys — Lesson - 3

This lesson covers the application of Ansys in solving thermodynamics problems. It delves into the understanding of processes such as heat transfer, work input, and entropy change in a condenser. The lesson also explains the concept of isentropic efficiency and how to calculate the rate of entropy generation. It uses a practical example of a problem involving saturated water vapor being steadily cooled as it flows through a constant pressure condenser. The lesson further explains how to use steam tables to determine states and how to apply the first law of thermodynamics to solve problems.
