Microcombustion techniques have emerged as promising methods for enhancing the efficiency of thermoelectric generators (TEGs) due to their ability to provide high heat fluxes and temperature gradients. Recent literature reviews have highlighted the significant impact of these techniques on TEG performance.
One of the key advantages of microcombustion is the ability to achieve high surface-to-volume ratios, which leads to improved heat transfer and thermal efficiency. By utilizing microchannels or porous media, microcombustion systems can create large surface areas for heat exchange, resulting in enhanced temperature gradients across the TEG device. This improved thermal efficiency translates directly to higher electrical power output.
Moreover, microcombustion techniques offer precise control over fuel-air mixing and combustion processes. This enables the optimization of combustion conditions, such as temperature and equivalence ratio, to maximize heat transfer and minimize heat losses. The precise control also allows for the use of alternative fuels, such as hydrogen or biofuels, which can further enhance TEG efficiency.
Recent review articles have emphasized the experimental and numerical studies that demonstrate the significant performance improvements achieved with microcombustion techniques. For instance, a 2021 review by Wang et al. concludes that microcombustion-based TEGs have the potential to achieve power densities several times higher than conventional TEGs. Similarly, a 2022 review by Li et al. highlights the ability of microcombustion to improve TEG efficiency by up to 20%.
