    A Comprehensive Review of Computational Fluid Dynamics Simulation Studies in Phase Change Materials: Applications, Materials, and Geometries
    (Springer, 2023) Soodmand, A. Mohammadian; Azimi, B.; Nejatbakhsh, S.; Pourpasha, H.; Farshchi, M. Ebrahimi; Aghdasinia, H.; Mohammadpourfard, Mousa; Heris, S. Zeinali
    Thermal energy storage systems (TESS) have emerged as significant global concerns in the design and optimization of devices and processes aimed at maximizing energy utilization, minimizing energy loss, and reducing dependence on fossil fuel energy for both environmental and economic reasons. Phase change materials (PCMs) are widely recognized as promising candidates due to their high latent heat storage (LHS) capacity. This review thoroughly evaluates the computational fluid dynamics (CFD) studies conducted in various sections, encompassing materials, modeling, simulation, as well as the results, advantages, and disadvantages of these works. The study is organized into three distinct sections. The first section discusses the applications of PCMs in various areas, including lithium-ion batteries, solar applications, building applications, electronics, and heating and cooling systems. The second section provides a comprehensive summary of cylindrical, rectangular, spherical, arbitrary shapes, and packed-bed geometries employed in TESS. The third section investigates the different types of materials used as PCMs. Based on the findings of this study, it can be concluded that industrial applications of hybrid nanocomposites incorporating PCMs in different geometries pose challenges, particularly in three-dimensional (3D) settings, where instability becomes a significant concern. Hence, further research and investigation are necessary to address these challenges adequately. In conclusion, this study serves as a reference review for future research endeavors in the field of simulating various PCMs in different geometries and applications. It provides valuable insights into the current state of knowledge, highlights potential areas for improvement, and offers guidance for advancing simulation techniques related to PCMs.

    Highly Efficient Treatment of Petrochemical Spent Caustic Effluent Via Electro-Fenton Process for Cod and Toc Removal: Optimization and Experimental
    (Springer, 2023) Gholami, Asma; Mousavi, Seyed Borhan; Heris, Saeed Zeinali; Mohammadpourfard, Mousa
    Caustic is commonly used in oil and gas refineries to remove CO2, H2S, organic sulfur, and acidic compounds; however, spent caustic must be treated considering the type of wastewater in refinery and petrochemical units due to their hazardous characteristics. This research aims to reduce the chemical oxygen demand (COD) and the total organic carbon (TOC) from the used caustic effluent of the olefin unit of Ilam Petrochemical Company employing the electro-Fenton method. The affecting parameters, such as H2O2 concentration, reaction time, pH, and current density on the COD and TOC removal rate, were investigated. An experimental design by response surface methodology (RSM) based on the Box–Behnken method with the considered factors was considered to study the setup’s effectiveness and optimize the conditions. The outcomes revealed that by increasing the H2O2 concentration from 11 to 18 mgL, the COD removal efficiency was enhanced from 68 to 93%. On the other hand, by increasing the reaction time after 15 min, the COD and TOC removal efficiency decreased. The same trend was observed by increasing the current density after the optimal value. The optimal conditions were acquired at pH = 4, current density = 20 mAcm2, H2O2 concentration = 18 mgL, and reaction time = 15 min. The promising results confirmed that the electro-Fenton could be an excellent treatment technique in Ilam Petrochemical Unit as a spent caustic treatment. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
