Energies 2021, 14, 204 that the load resistance ratio must be greater than one; however, the study did not deter- mine this value. From previous studies in the open literature regarding TEG systems for automotive exhaust, it is apparent that their main limitations are their very low densities of waste heat and their improper design despite the system’s size. The current study presents an ana- lytical design and experimental validation for a TEG system that captures waste heat from the exhaust of semi-trucks’ engines which travel for long distances between destinations, steady flow rates. The proposed design focuses on maximizing the electrical power output the exhaust of semi-trucks’ engines which travel for long distances between destinations, frsoumbsethqeuTenEtGlyspyrsotevmidibnygocpotnimtinizuionugsthweaesltechtreiactalexlohadusret sgiastsaantcceoansswtaenltl taesmthpernautumrbeseranofd thsteramdoyeflleomwernatseso.fTthe TpEroGpmosoedudles.iTghnefoTcEuGsesyosntemaixsiamnizainr-gtot-hleiqeuliedctsryicsatlempo,wehreoruetphuet cforolmingthleiqTuEiGd issysetxetmracbtyedopfrtoimiztihnegctohoeleinlegctsryicsatelmloaodf rtehseisetnangcineeasinwoerldl aers thoeanbusomrbetrhoef htehaetrfmromeletmheecnotsldosfitdheoTfEtGhemToEdGu.lTeo.TmhaexTimEGizesytshtemexpisloaintaatiro-ntoo-lfiqthueidexshyastuesmtg,wash,earheetahte scinokolisnugsleiqdu,iwdiitshepxatracmteedtefrsomsuctheacsofoinlinthgicskynstesmsaonfdthfeinesnpgaincienignoprdtiemritzoeadbusosirnbgthaeclhaesa-t sfircoamlanthaelyctoicldalsmidoedoefl.thAeuTnEiGt.cTeollmofatxhimeTizEeGthseyesxtepmloiwtaatisomnodftehlledex,haanudsthgeans,taheheraetsusilntsk wiseruesedxt,rwapitohlaptaerdamtoedtertsersmucinheatshfienrethsuiclktsnfeosrs tahnedwfihnoslepascyisntgemop.

The location of the TEG system in the gas and transfers it to the hot side of the modules, and a heat exchanger that dissipates the exhaust pipe is crucial to the system’s performance, where it has to be ideally located as heat from the cold side of the modules. The location of the TEG system in the exhaust pipe close as possible to the catalytic converter to allow maximum exploitation of the steady is crucial to the system’s performance, where it has to be ideally located as close as possible heat emitted [16]. to the catalytic converter to allow maximum exploitation of the steady heat emitted [16].

Thermoelectric Unit Cell Design To simplify the proposed model, the system was divided into TEG system unit cells. The design of the TEG cell was modelled analytically by six governing Equations (1)–(6). Figure 2 shows the thermoelectric module placed between the heat exchanger (the hot side) and the heat sink (the cold side).
