    CFD-DEM Modeling of Biomass Pyrolysis in a DBD Plasma Fluidized Bed
    (Pergamon-Elsevier Science Ltd, 2025) Eslami, Ali; Kazemi, Saman; Hamidani, Golnaz; Zarghami, Reza; Mostoufi, Navid
    This study developed a CFD-DEM model to simulate biomass pyrolysis within a dielectric barrier discharge (DBD) plasma fluidized bed reactor. Biomass, as a renewable energy source, offers a promising alternative for hydrogen production through pyrolysis. The integration of non-thermal plasma technology and fluidized bed reactors is expected to enhance conversion. Key operational parameters such as inlet gas velocity, particle size, and input voltage were examined to evaluate their effects on temperature distribution, particle conversion, and hydrogen production. Results indicated that higher inlet gas velocities promote better particle mixing and more uniform temperature and conversion distribution. Smaller particle sizes significantly enhance biomass conversion by increasing the available surface area between fluid and particles. Specifically, particles with diameters of 0.85, 1.2, and 1.5 mm achieved conversions of 10.4, 8.99, and 8.57 %, respectively, at 20 s from the start of the process. Additionally, increasing the input voltage increases the mean temperatures of particles and fluid, which enhances reaction rates and conversion. Optimizing these parameters can improve the efficiency of DBD plasmaassisted biomass pyrolysis, providing valuable insights for sustainable hydrogen production.

    Future Trends of Hybrid Energy Systems
    (Elsevier, 2024) Taheri, M.H.; Seiiedhoseiny, M.; Mohammadpourfard, M.; Akkurt, G.G.
    Hybrid energy systems can be defined as a combination of at least two fuel sources or energy conversion equipment that, when combined, can eliminate the constraints related to every single component. In addition to the application of multiple renewable energy sources, the improvement of energy efficiency via multi-generation plants constitutes a significant share of the recent investigations, which would include a prominent part of the future trend in hybrid energy systems. The present chapter will review the pioneer works and tries to address the future of hybrid energy systems. © 2024 Elsevier Inc.
