- Undertake experimental evaluation of thermal plant and energy systems.
Learning Outcomes
Having successfully completed this module you will be able to:
- C1 M1 All assignments require students to apply thermodynamic principles to solve complex mathematical problems relating to machinery in current regular usage in the real world, e.g. spark ignition engines, gas turbines, steam turbines, combined cycle power plants, air conditioning systems, heat pumps. C2/M2 In both the engine and refrigerator practicals students must obtain their own data, then numerically analyse that data to reach conclusions on the performance of the systems. They must discuss their results in the context of their wider thermodynamics knowledge, and how practice differs from theory. C3 Students must select appropriate models and/or equations and use them to solve thermodynamics problems in final exam and the engine and refrigerator practicals. Within these students must address expected differences between theory and “real world” results .Computational methods are also used in the “power plant analysis” coursework. C12/M12 In engine practical students must use various measurements to quantify engine performance and determine whether the engine is performing consistently with theory. C13/M13 Questions within the final exam and “Power plant analysis project” coursework explores limitations of engines relating to material properties (e.g. max temperatures for steam turbines). C6 When analysing air conditioning units or combined cycle power plants (both assessed in final exam) students must apply knowledge of how different thermodynamic processes work together. C7 Engine practical includes questions on how to minimise local pollution via use of catalytic convertors and how engine operation (e.g. lean vs rich) affects their operation.
