Independent parallel reactions (IPR) and distributed activation energy (DAEM) kinetic models were developed and compared for the combined pyrolysis-gasification of two agro-industrial waste materials. The aim was to recycle greenhouse gas carbon dioxide for mitigating emissions, to evaluate the thermal behavior, reactivity, conversion and product composition in terms of structural/chemical characteristics of the fuels, and to provide accurate kinetic parameters useful in the scaling-up of the pr [...]

Parabolic trough collectors (PTCs) are essential for solar thermal energy systems, and their thermal efficiency can be significantly enhanced using turbulators and nanofluids. This numerical study introduces three novel fin-spiral turbulator configurations (4, 7, and 10 blades) to enhance heat transfer within the absorber tube. Additionally, three nanofluid types including water-based single-walled carbon nanotubes (SWCNT), cupric oxide (CuO), and a hybrid SWCNT-CuO, at concentrations of 1%, 3%, [...]

Performance degradation, including system deterioration, corrosion, and energy loss in solar PV systems, can be caused by environmental conditions such as high humidity, frequent rainfall, and temperature swings in tropical nations. Over the years, photovoltaic energy has been successfully developed to have low production costs and high efficiency. It has been the main reason that solar energy is one of the fastest-growing renewable energies in the world, with a generation of 821 TWh of electric [...]
