  1. MAE 431 Energy System Fall 2002 Dr. Hui MengKnox 104MWF 8:00am http://www.eng.buffalo.edu/Courses/mae431/

  2. How to study this course (similar to MAE335) • Before Class • Read (at least look at) assigned sections • In Class • Do not try to take detailed notes • Listen to, fill in, and understand what you have read • Write down key words for concepts, definitions, problem solving techniques, etc. so you know what to emphasize when reading the book. • Ask questions

  3. How to study this course • After Class • Study key concepts – write out definitions and descriptions • Work assigned problems – simultaneously study theory and example solutions • Go to recitations only after you have tried to work the problems yourself. The TA will only give you hints when you are lost; they will not solve the homework problems for you. The TA may provide additional examples.

  4. Examples of Energy Systems • Power Generation • Automobile engines (Ch. 9) • Fossil- & nuclear-fueled power stations (Ch. 8,9) • Propulsion systems for aircraft & rockets (Ch.9) • HVAC systems • Vapor compression refrigeration (Ch. 10) • Heat pumps (Ch. 10) • Air-conditioning (Ch. 12) • Reacting systems • Combustion (Ch. 13)

  5. Examples of Energy Systems (cont’d) • Cooling of electronic equipment • Alternative energy systems • Fuel cells • Thermoelectric and thermionic devices • Magnetohydrodynamic (MHD) converters • Solar-activated heating, cooling, and power generation • Geothermal systems • Ocean thermal, wave, and tidal power generation • Wind power • Biomedical applications • Life-support systems • Artificial organs

  6. Automobile Engine

  7. Electrical Power Plant

  8. Turbojet Engine
