Step-by-step explanation:
The correct answer is option Physics.
Thermodynamics is the branch of physics that deals with energy transfer involving physical matter. A thermodynamic system is the matter under consideration, and everything outside of that matter is called the surroundings. One example of a thermal energy system with a heat exchanger is an air conditioner.
In this system, the heat exchanger plays a crucial role in transferring heat between the indoor and outdoor environments, allowing the air conditioner to cool the indoor space.
The correct answer to the selection of a thermal energy system with at least one heat exchanger is a heat engine, such as a steam power plant. In this system, a heat exchanger is utilized to transfer heat from a high-temperature source to convert water into steam, which then expands through a turbine to produce work.
The steam is subsequently condensed back into water in another heat exchanger called a condenser, where heat is ejected to a sink.
Heat engines operate on the basis of thermodynamics, where energy is transformed from heat into work. An exergy analysis evaluates the efficiency and quality of energy transformations within the system.
This analysis is crucial in the design and assessment of the heat exchangers to maximize the system's performance and identify areas for improvement.
During the analysis, it is essential to define the system boundaries, identify the components (boiler, turbine, condenser, and pump), as well as the heat and work interactions. A detailed energy flow diagram is instrumental in understanding the process.
The design and function of the heat exchangers must ensure optimal heat transfer while minimizing exergy destruction to achieve high system efficiency.
