Suggested Student Activities:
Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (students) portfolio which will be useful for their placement interviews:
- Prepare a power point presentation on emission norms.
- Make charts for performance characteristics of IC Engine.
- Make a chart showing heat balance sheet format to display in laboratory.
- Collect specifications of gas turbine based engines used for power generation and for jet engines.
- Collect specifications of domestic refrigerators and window air-conditioners from manufacturers websites.
- Collect information on different tests actually used for IC engines.
- Measure DBT and WBT using thermometer and calculate rest of the properties of air using psychrometric chart.
- Prepare trouble shooting chart for domestic refrigerator I window air-conditioner
- Prepare electrical trouble shooting chart for refrigeration system.
- Prepare trouble shooting chart for IC engine.
- Prepare seminar report on dual fuel and hybrid engines.
- Visit an industry where air compressors are monitored online using SACDA or similar system. Write a report on the same.
- Collect IC Engine fuel characteristics including information on RON and MON.
Suggested Special Instructional Strategies:
These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course:
- Massive open online courses (iMOOCs) may be used to teach various topics/sub topics.
- ‘L’ in item No. 4 does not mean only the traditional lecture method, but different types of teaching methods and media that are to be employed to develop the outcomes.
- About 15-20% of the topics/sub-topics which is relatively simpler or descriptive in nature is to be given to the students for self-directed learning and asst^sthe development of the COs through classroom presentations (see implementation guideline for details)
- With respect to item No. 10, teachers need to ensure to create opportunities and provisions for co-curricular activities.
- Guide students in undertaking micro-projects.
- Correlate subtopics with power engineering system utility and equipment.
- Use proper equivalent analogy to explain different concepts.
- Use Flash/Animations to explain various working of compressor, gas turbine and refrigerant flow in refrigerator and air conditioner.
- Show different parts of various refrigeration and air conditioning units.
- Show constructional details of various Gas turbines, Jet Engines, Reciprocation and Rotary Compressors.
