“…Additionally, NACA 4424 and NACA 23024 share the third position, indicating their equally strong suitability for small-scale wind turbine blade applications. It's worth highlighting that our results diverge from single-objective selection methods used in prior research, such as SG6043 and SG6042 (Noronha & Krishna, 2021;Salgado et al, 2016), as well as from the most commonly employed airfoils for small-scale wind turbines, including NACA 0012, NACA 0015, NREL S825, and NREL S833 (Hazmoune et al, 2021). Since the wind turbine works under complex operational conditions, we highly recommend the airfoil selected using multi-criteria decision-making methods.…”

Over the last century, the growing demand for clean energy has emphasized wind energy as a promising solu-tion to address contemporary energy challenges. Within the realm of wind energy, the wind turbine plays a pivotal role in harnessing the kinetic energy of the wind and converting it into electrical power. Among the various components of the wind turbine system, turbine blades assume a critical role in capturing the wind's kinetic energy and converting it into rotational motion. Consequently, the design of wind turbine blades holds the utmost importance in determining the overall performance and efficiency of the entire wind turbine system. One essential aspect of blade design involves selecting an appropriate airfoil. Throughout history, numerous airfoil profiles have been developed for various applications. Notably, National Advisory Committee for Aeronautics (NACA) and National Renewable Energy Laboratory (NREL) airfoils have been tailored for aircraft and large-scale wind turbine blades, respectively. However, the quest for suitable airfoil types for small-scale wind turbine blades has been ongoing. This study delves into an examination of over 62 distinct NACA and NREL aerofoil types tailored for small horizontal-axis wind turbine blades. Employing specialized software, namely QBlade, specifically designed for modeling and simulating wind turbine blades, the study calculates key parameters such as power output, stress, deformation, and weight for each airfoil. Subsequently, based on the simulated data, the optimal airfoil is identified using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) multi-criteria selection approach. This selection process takes into account simulation results pertaining to power output, stress, deformation, and weight. The decision-making process involving multiple criteria is facilitated using Excel and Python. The findings of this study reveal that among the 62 airfoil types under consideration, the NACA 0024, NACA 2424, and NACA 4424 airfoils emerge as the most suitable choices for small horizontal-axis wind turbine blades.

“…In relation (20), the values for 𝑉 𝐶𝑂 2 𝑜 and 𝑉 𝑎 𝑒𝑥 are determined by the calorific value of the fuel and the excess air λ, respectively. For certain values of the excess air, the ignition conditions are not met [12], [13], [14], [15]. For a single combustible gas (H2), the limits of the ignition concentrations have the lower and upper value as follows: 𝐶 𝑖 = 4.1% and 𝐶 𝑠 = 74%.…”

The efficiency of the direct methanation of the flue gases from the energy installations is influenced both by the relatively low participation of the CO2 component and by the presence of water vapor and oxygen from the excess air. The water vapor content reduces the efficiency of the methanation process by a small percentage. The excess air has been analysed in the paper in more detail to determine whether it can lead to the process of self-ignition (explosion) of hydrogen in the phase of its admission to the methanizer. Thus, an analytical calculation was performed for the composition of the flue gases from an energy installation that uses liquid fuel, the excess air being 1.3. At the end of the paper, the objectives of the experimental tests to be performed were presented, and details regarding the complex experimental installation and the already achieved methanizer were provided.
