Thermoelectric Generation System For The Property Of Engine

With the rapid development of science and technology, the car has been a common traffic tool. The large number of used cars not only narrowed the distance between people, but also promoted the economy and society. However, cars caused many problems along with the benefits, such as cars consume a large number of oil, auto emissions do great harm for our environment. Therefore, people are paying more and more attention to energy saving and emission reduction, related technologies are constantly being developed and applied to vehicles.For the limitation of current engine technology, about sixty percent of energy hasn’t been effectively utilized of the fuel, most of the fuel energy are wasted in the form of heat and discharge into the atmosphere. In today’s automotive energy saving trend, the technology of transferring thermal energy into electric energy is becoming more and more important, which has great significant for cars energy saving and emission reduction. Thermoelectric generation system have many advantages such as a small size, long life, no noise, no pollution, no rotating parts, etc, which attracted many attentions from scientists and automotive experts.In this paper, our research object is vehicle engine. The main contents include the following four parts:First. Described the research status and development direction of thermoelectric technology and expounded some basic concepts. Analysis the thermoelectric generator’s maximum output power and maximum output efficiency under three different conditions.Second. Basing on the engine simulation software of AVL-BOOST and dates provided by the engine factory, we established the engine model, input many parameters into corresponding components and calibrated the model. Then we obtained the fluid’s temperature, pressure and speed in the engine exhaust system.Third. Using the software of Pro/E to create three-dimensional model of the thermoelectric and meshing it with the software of ICEM CFD. Then, import the meshing into STAR-CD and finished the simulation and analysis.Fourth. Obtained the relevant position’s parameters of the exhaust system and compared with the preceding research and analysis it through the vehicle engine experiment. Laid the foundation for further study.
