“…The airflow that enters through an external casing interacts with the turbine blade tangentially and exits the casing via a chimney [57]. A design with initial optimization using computational fluid dynamics (CFD) simulation and response surface modeling with applications of machine learning algorithms was suggested in 2018 by Wang et al [58]. Furthermore, artificial-neural-network-assisted meta-modeling to optimize the shape was proposed by Sarkic-Glumac et al in 2018.…”

Alternative energy is a rapidly expanding research area primarily driven by concerns over pollution caused by inefficient conventional energy sources. However, many developing nations rely heavily on these conventional sources. In response, numerous researchers have focused on developing kinetic energy recovery systems (KERS) to capture and utilize the energy lost due to inefficiency. These KERS can be implemented in various scenarios, such as near railroad tracks, industrial flue stacks, cooling towers, and air conditioning outlets. The primary objective of this paper is to critically and comprehensively evaluate the research conducted on the development of these systems. The review reveals that the wind speed in the studied cases ranged between 15 and 22 m/s, providing a consistent and theoretically maximum potential higher than any location worldwide. Furthermore, the impact of these systems on the Betz limit, as well as their drawbacks and crucial advancements necessary for practical implementation, have been thoroughly assessed. This paper contributes to the existing body of knowledge by presenting a comprehensive analysis of the research conducted on KERS development. It highlights the potential of these systems in harnessing untapped energy sources and identifies key areas that require further attention for successful practical application.

“…A venturi-shaped form with a streamlined body was proposed as an outcome of validation which gave a better amplification effect when compared to other configurations. Qiang Wang et al 24 computed the airflow over buildings in urban residential areas using lidar measurements. They validated the effect of turbulence, wind acceleration, and turbulence thickness on wind performance.…”

To address the future growth in energy demands, complete renewable power generation from environmental assets demands unique methodologies from every investigator. Wind energy harvesting in residential areas is one such approach. But the urban landscape and the physical challenges restrict the erection of small-scale wind turbines. Further, a significant degree of uncertainty leads to a lack of awareness of how dispersion in urban environments impacts turbine performance. This research looks into the potential productivity of wind turbine installations in urban areas, considering turbulence. These unique ambient conditions prevailing in a dynamic environment compared to flat terrains have made the harnessing of wind energy very difficult. Many researchers are still trying to find an effective methodology in these constrained circumstances. Since the characteristics of small-scale wind turbine models are undetermined, large-scale turbines fared well compared to small-scale wind turbine models. The feasibility and success of small and medium turbines in community homes were investigated in this study. The origins of the very uncertain nature of atmospheric boundary layer limitations are discussed in this work and subsequent successful developments by different researchers.

“…CFD based numerical simulations are carried out for the calculation of Annual Energy Production (AEP). The research method based on Computational Fluid Dynamics has shown its applicability in wind energy studies [21,22]. For a comprehensive study of the issue, two different wind park sites, three wake turbulence models and seasonal climatologies were used for the numerical simulations.…”

This paper describes a case study of wind resource assessment and wind park design at Solovetsky Islands, which are located in the Arctic region of northern Russia. The Solovetsky historical and cultural complex has been included in the list of UNESCO's World Heritage Sites. 18 year's data of wind climatology from the NASA Langley Research Center (LaRC) is used for wind resource assessment at Solovetsky Islands for two different wind park locations. Computational Fluid Dynamics (CFD) based numerical simulations are carried out for wind resource assessment and for the estimation of the resultant Annual Energy Production (AEP) for both locations. To better understand wind flow physics and effects of wind turbine wake effects, three different wake models are used for the numerical simulations. Analyses of seasonal weather effects on energy production show that wind power production at Solovetsky Islands is higher during winter period as compared to summer period, mainly due to higher wind speeds and air density at cold winter conditions. A preliminary case study about wind park layout optimization has also been carried out, where results show an increase in AEP with the optimization of wind park layout.
