This paper shows the energy analysis of a thermoelectric system coupled to a turbofan engine, which is based on the mathematical modeling of the heat transfer of the system during the cogeneration process using fluid dynamics (CFD). The use of waste heat from a turbofan engine would allow us to increase its efficiency which has both economic (due to fuel savings) and environmental (reduction of polluting gases). The proposed section for the installation of the thermoelectric system is the one that covers the turbine and the nozzle section of the turbofan engine, since they are sections in which there are better operating temperatures, in the order of 600 to 200oC. As results of the CFD simulation you get the distribution of temperatures through the thermoelectric and the difference of electrical potential generated. These results determine the overall efficiency of the system and the electrical energy generated by the waste heat. The energy generated by the thermoelectric system can be used in secondary aircraft systems, such as the lighting system, entertainment, etc. The importance of the analysis lies in increasing the overall efficiency of the engine combustion process, to reduce fuel consumption and the costs associated with it.
