This model is capable of computing the overall heat transferred, the electrical power output, and the associated pressure drop for given inlet conditions of the exhaust gas and the available TEG volume. Multiple-filled skutterudites and conventional bismuth telluride are considered for thermoelectric modules (TEMs) for conversion of waste heat from exhaust into usable electrical power. Heat transfer between the hot exhaust gas and the hot side of the TEMs is enhanced with the use of a plate-fin heat exchanger integrated within the TEG and using liquid coolant on the cold side. The TEG is discretized along the exhaust flow direction using a finite-volume method. Each control volume is modeled as a thermal resistance network which consists of integrated submodels including a heat exchanger and a thermoelectric device. The pressure drop along the TEG is calculated using standard pressure loss correlations and viscous drag models. The model is validated to preserve global energy balances and is applied to analyze a prototype TEG with data provided by General Motors. Detailed results are provided for local and global heat transfer and electric power generation. In the companion paper, the model is then applied to consider various TEG topologies using skutterudite and bismuth telluride TEMs. TMS, 2013 Thermoelectric generators nationallicence waste heat recovery nationallicence automotive exhaust nationallicence skutterudites nationallicence Kumar Sumeet School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut Heister Stephen School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut Xu Xianfan School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut Salvador James General Motors Global R&D, Warren, MI, USA aut Meisner Gregory General Motors Global R&D, Warren, MI, USA aut Journal of Electronic Materials Springer US; http://www.springer-ny.com 42/4(2013-04-01), 665-674 0361-5235 42:4<665 2013 42 11664 https://doi.org/10.1007/s11664-013-2471-9 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s11664-013-2471-9 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Kumar Sumeet School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut NATIONALLICENCE 700 1- Heister Stephen School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut NATIONALLICENCE 700 1- Xu Xianfan School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA aut NATIONALLICENCE 700 1- Salvador James General Motors Global R&D, Warren, MI, USA aut NATIONALLICENCE 700 1- Meisner Gregory General Motors Global R&D, Warren, MI, USA aut NATIONALLICENCE 773 0- Journal of Electronic Materials Springer US; http://www.springer-ny.com 42/4(2013-04-01), 665-674 0361-5235 42:4<665 2013 42 11664 Metadata rights reserved Springer special CC-BY-NC licence nationallicence SWISSBIB 51080084X BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
