Hands-On Experience with Rankine Cycle in the Thermal Science Laboratory Course
Thermal Science laboratory is the third course in the sequence of four mechanical engineering laboratories offered by the Mechanical Engineering Department at North Carolina A&T State University University. The course is one credit hour, meeting once a week for two hours. The course includes selected experiments on heat transfer and thermodynamics.
In an effort to give students a combination of theoretical background and hands-on experience, a new experiment on Rankine Cycle was introduced. This paper describes the experiences the students gained in the concepts of thermodynamic cycles, mass and energy conservation and electrical power generation. During this laboratory the students actually learned how to operate a table top steam-electric power plant; collected and analyzed the output data that included heat rate calculations, cycle efficiency, turbine efficiency & energy balance studies, and related the experimental result to the theory learned in the thermodynamics course.
This experiment complemented the thermal science laboratory course and fully integrated some aspects of thermodynamics and enhanced the student’s learning process. The broader educational objectives are to improve the students’ understanding of thermodynamics, to help them integrate this knowledge with other subjects, and to give them a better basic understanding of the first and second law of thermodynamics. Practically speaking, it also gives them insight into the actual operation of a steam turbine electrical generation power plant, which may inspire some to eventually pursue a career in this field.
This experiment is designed to give the students a hands-on experience with a Rankine Cycle, and to directly relate the mechanical device to the theory learned in a typical thermodynamics course. This paper describes the experiences the students gained in the areas of thermodynamics and power generation. The laboratory introduces the students to the basic principles of a real steam power plant. During this experiment the students actually learn how to operate a table top steam power plant, collect and analyze the output data and relate the result to the theory learned in the thermodynamics courses. The broader educational objectives are to improve the students’ understanding of thermodynamics, to help them integrate this knowledge with other subjects, and to give them a better basic understanding of how a steam power plant works that include:
≠ Energy relationships and the First Law of Thermodynamics. ≠ Cycle analysis and the Second Law of Thermodynamics. ≠ Control volume analysis. ≠ Entropy analysis. ≠ Isentropic analysis and the study of turbine/nozzle efficiency.
