To increase the efficiency and economic viability of TEGs, research is performed on the materials on one hand and on the system connection on the other. In the latter case, the net output power of the cooling system plays a key role. At first glance, passive cooling seems preferable to active cooling because it does not affect the net electrical output power. However, as shown in the present review, the active cooling is to be preferred for net output power. The situation is similar in air and water-cooling. Even though air-cooling is easier to set up, the water-cooling should be preferred to achieve higher net output power. It is shown that microchannel cooling has similar hydraulic performance to conventional cooling and inserts increase the net output power of TEG. As the review reveals that active water-cooling should be the method of choice to achieve high net output power, it also shows that a careful optimization is necessary to exploit the potential.}, language = {en} } @article{PfeiffelmannOezmanBenimetal.2019, author = {Pfeiffelmann, Bj{\"o}rn and {\"O}zman, Cansu and Benim, Ali Cemal and Joos, Franz}, title = {Variable temperature effects on TEG performance}, series = {E3S Web of Conferences}, volume = {128}, journal = {E3S Web of Conferences}, publisher = {edp sciences}, issn = {2267-1242}, doi = {10.1051/e3sconf/201912807004}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27893}, year = {2019}, language = {en} } @article{BenimGuelAssmannetal.2016, author = {Benim, Ali Cemal and G{\"u}l, Fethi and Assmann, Alexander and Akhyari, Payam and Lichtenberg, Artur and Joos, Franz}, title = {Validation of loss-coefficient-based outlet boundary conditions for simulating aortic flow}, series = {Journal of Mechanics in Medicine and Biology}, volume = {16}, journal = {Journal of Mechanics in Medicine and Biology}, number = {2}, publisher = {World Scientific}, doi = {10.1142/s0219519416500111}, year = {2016}, language = {en} } @article{BenimIqbalJoosetal.2016, author = {Benim, Ali Cemal and Iqbal, Sohail and Joos, Franz and Wiedermann, Alexander}, title = {Numerical Analysis of Turbulent Combustion in a Model Swirl Gas Turbine Combustor}, series = {Journal of Combustion}, volume = {2016}, journal = {Journal of Combustion}, publisher = {Hindawi}, issn = {2090-1968}, doi = {10.1155/2016/2572035}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-28044}, pages = {1 -- 12}, year = {2016}, language = {en} } @article{PfeiffelmannBenimJoos2018, author = {Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of liquid jet impingement cooling of a thermoelectric generator}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001032}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27988}, year = {2018}, language = {en} } @article{IqbalPfeiffelmannBenimetal.2018, author = {Iqbal, Sohail and Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {Numerical analysis of lifted hydrogen flame}, series = {MATEC Web of Conferences}, volume = {240}, journal = {MATEC Web of Conferences}, publisher = {edp sciences}, issn = {2261-236X}, doi = {10.1051/matecconf/201824001014}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-27950}, year = {2018}, language = {en} } @article{BenimEscudierNahavandietal.2010, author = {Benim, Ali Cemal and Escudier, Marcel and Nahavandi, Ali and Nickson, A.
