Assignment: Investigate applications of thermodynamic systems

B.P4 Explain the differences between open and closed loop thermodynamic systems used in given engineering applications
B.P5 Calculate work done, thermal energy transfer and efficiency in given open and closed loop thermodynamic systems
B.M3 Analyse, using the First and Second Laws of thermodynamics, open and closed loop thermodynamic systems in given engineering applications, calculating work done, energy transfer and efficiency accurately
B.D2 Evaluate, using the First and Second Laws of thermodynamics, open and closed loop thermodynamic systems in given engineering applications, calculating work done, energy transfer and efficiency accurately

Scenario:

Your supervisor is pleased with the work that you have done in producing your report that explains the principles of thermodynamics. He would now like you to investigate open and closed loop thermodynamic systems. He would also like you to examine energy transfer within the systems and consider how the laws of thermodynamics are applied to these systems. He would then like you to consider the relationship between thermodynamic principles and parameters and then perform calculations to determine values related to thermal energy for the systems.

You are now to produce a written report which:
a) explores given applications of open- and closed-loop thermodynamic systems,
b) applies the laws of thermodynamics to calculate work done, thermal energy transfer and system efficiencies for given thermodynamic systems, and
c) evaluates the laws of thermodynamics and how these are applied to the given thermodynamic systems.
To do this.
Your tutor will provide you with examples of open-loop and closed-loop thermodynamic systems that you are to research and investigate, along with suitable data that will allow you to carry out calculations to an appropriate degree of accuracy and using appropriate units throughout. Your report should contain:
• research into your given applications of thermodynamic systems and identify the similarities and differences between the open- and closed-loop systems.
• calculations to determine the values of (using the data provided for both a Stirling engine and a heat exchanger):
a. work done in the system
b. output energy from the system
c. energy losses from the system
d. overall system efficiency
e. overall thermal energy transfer.
Using the results of your calculations you then need to produce a balanced evaluation of how the First and Second Law of Thermodynamics are applied to your given open- and closed-loop thermodynamic systems.
You should:
a) consider the interrelationships of the thermodynamic principles and parameters which act on the two systems,
b) consider the advantages and disadvantages of the two different types of system
c) explain the significance of energy losses on the efficiencies of your given systems, referring to your calculations, and
d) provide a suitable conclusion
