  1. MECG-1460 : Introduction to Thermal Sciences

  2. Instructor Information Instructor: Dr. Bing-Chen Wang Email: BingChen.Wang@ad.umanitoba.ca Tel: (204) 474-9305 Office: E1-488 There will be three Teaching Assistants (TA), who can also be consulted when you have questions regarding the course study.

  3. What is “Thermodynamics” ? Simple??? Yes??it is all about “Thermo” and “Dynamics”. The word “thermodynamics” stems from the Greek words “therme” (heat) and “dynamis”(power). No??Today the same name is broadly interpreted to include all aspects of energy, energy transformations and properties of a substance. Thermodynamics is both a branch of physics and an engineering science, and is closely related to the science of heat and mass transfer, fluid dynamics, and mechanical, chemical, civil and electrical engineering.

  4. Selected Areas of Applications • Automotive engines; • Gas turbines, turbo-engines; • Steam power plants, hydraulic power plant; • Compressors, pumps; • Combustion chamber, boilers; • Engines for aircrafts, space shuttles and rockets; • Design of submarine: engine & environment; • Cryogenics: Cryofuel, simulation of outer space environment natural gas separation & liquefaction, oil refinery & distillation; • HVAC: heating, ventilating and air-conditioning, refrigeration; • Alternative energy: fuel cells, bio-mass, solar energy, windmills, geothermal system, tidal power; • Nuclear energy: power plants & engines.

  5. Example 1: Steam Power Plant Siemens Steam Plants (SSP™) Reference: http://www.powergeneration.siemens.com/products-solutions-services/power-plant-soln/steam-turbine-power-plants/

  6. Example 1: Steam Power Plant

  7. Example 2: Tidal Stream Turbine Tidal power is the only form of energy which derives directly from the relative motions of the Earth-Moon system. Tidal power is practically inexhaustible and classified as a renewable energy source. Tidal energy is periodical and predictable. In contrast, wind and solar energies cannot be well-predicted. SeaGen is the world's first large scale commercial tidal stream generator. It is four times more powerful than any other tidal stream generator in the world. Reference: http://en.wikipedia.org/wiki/SeaGen

  9. Example3: Cryofuel -- Liquefied Natural Gas & Hydrogen “15 April, 1988 the aircraft performed its maiden flight using liquid hydrogen. Upon flight testing and development 18 January, 1989 TU-155 a/c performed its first flight on liquefied natural gas. Large flight testing Program was fulfilled, several international flight demonstrations were made including those to Bratislava (Czhekoslovakia), Nice (France), Berlin and Ganover (Germany).” Reference: TUPOLEV (A Russian Company for Cryogenic Air Craft) http://www.tupolev.ru/English/Show.asp?SectionID=27

  10. Example 4: Cryofuel --Liquid Hydrogen & Oxygen U.S. space shuttle, composed of a winged orbiter, an external liquid-propellant tank, and two solid-fuel rocket boosters. Reference: Britannica Encyclopedia Online http://www.britannica.com/

  11. Example 5: Cryofuel -- Liquid Hydrogen “BMW Hydrogen 7, a luxury 7-Series sedan powered by a 6.0-litre V-12 engine whose emissions are cleaner than the air you breathe.” To store its hydrogen fuel, there is a 30-millimetre-thick, 200-kg cryogenic fuel tank capable of holding 170 litres of liquid hydrogen at -253 degrees.
