In this study, the aerodynamic coefficients of NERL S826 airfoil, used for small-scale wind turbines, are numerically computed. To account for high skewness at a high angle of attack, an unstructured mesh with two different turbulence models, namely The k- $omega$ SSt and Spalert-Allmaras was implemented using the OpenFOAM-2206 tool. The simulation results are validated against wind tunnel experimental data obtained in the same flow conditions. Moreover, the results also are compared with other numerical simulations conducted for the same type of airfoil using an OpenFOAM-06 with a structured mesh. Additionally, blade element theory (BET) was considered in the comparison of the aerodynamic characteristics. It was found that the results for the drag coefficients achieved by OpenFOAM-2206 simulation for both turbulence models are in less agreement with the experiment in comparison with those obtained by OpenFOAM06, particularly for the AOA in the range of $0^{circ}-12^{circ}$. However, a better prediction of the drag coefficients was achieved for higher AOA by OpenFOAM-2206 simulation with the k- $omega S S T$ model and unstructured mesh compared with the other methods. On the other hand, an excellent agreement between OpneFOAM-2206 results in the lift coefficients with the experiment was obtained in comparison with the other methods.
在这项研究中,气动系数的NERL S826翼型,用于小型风力发电机,是数值计算。为了解决大迎角下的高偏度问题,使用OpenFOAM-2206工具实现了具有两种不同湍流模型(即k- $omega$ SSt和Spalert-Allmaras)的非结构化网格。仿真结果与相同流动条件下的风洞实验数据进行了对比验证。此外,结果还与其他数值模拟进行了比较相同类型的翼型使用OpenFOAM-06与结构网格。此外,在气动特性比较中考虑了叶片单元理论(BET)。结果表明,与OpenFOAM06相比,OpenFOAM-2206对两种湍流模型的阻力系数模拟结果与实验结果不太吻合,特别是在$0^{circ}-12^{circ}$范围内的AOA。然而,与其他方法相比,采用k- $omega S S T$模型和非结构化网格的OpenFOAM-2206模拟可以更好地预测更高AOA的阻力系数。另一方面,与其他方法相比,OpneFOAM-2206的升力系数计算结果与实验结果吻合良好。

In Gaza Strip, power outages lasting several hours daily are very common. In addition, today’s power systems are facing challenges of environmental protection, increasing global power demand, and high reliability requirements. Centralized plants are now being replaced by smaller, distributed plants to pave the way to green and intelligent energy systems. The microgrid concept can therefore be viewed as a group of distributed energy loads and resources that can operate as a single controllable system and encompass many renewable energy sources and energy storage systems. For the microgrid system to operate reliably, energy management of a large number of distributed energy resources is required. As a result, energy management is a critical component of microgrid operation for economic and sustainable development. In this paper, the primary goal is to look into the feasibility of installing a microgrid system for Nasser medical complex. A techno-economic analysis of the capex, savings, and financial benefit of numerous microgrid possibilities is used to justify the final design. Using the HOMER Pro tools, several scenarios and architectures were simulated and discussed in terms of their specific requirements, features, and drawbacks. The scenarios are based on different alternatives, such as replacing a plant (which consists of a diesel generator) with a solar photovoltaic (PV) system and a battery-backed energy storage system (BESS). The simulations show that Scenario 4 (Hybrid PV system with Li-Ion batteries) is the optimal configuration regarding the economic indicators. The results clearly demonstrate that an annual grid power cost of 1.70M${$}$, fuel costs of 0.40 M${$}$, and operating costs of 0.66M${$}$, with an annualized savings of 0.36 M${$}$. The hybrid approach proposed in this situation has a 48.5% IRR, a payback period of 2.06 years, and an LCOE of 181 ${$}$/MWh.

Globally, solar energy is a source of renewable energy that is expanding quickly. To produce power, renewable energy technologies like photovoltaic cells are increasingly being advised as concern about greenhouse gas emissions and environmental issues rises. Bangladesh currently has 650.53 Megawatts of installed renewable energy capacity. A unique possibility for renewable energy in the nation exists at the Port of Payra in Kalapara, Patuakhali, Bangladesh, which receives an average daily solar radiation of 4.34 kWh/m$^{mathbf{2}}$ per year. In this particular region, the location boasts several major internal strengths, such as its wide channel, river connectivity, and transportation infrastructure, which make it a place of tremendous potential. This study investigated and showed the total energy produced by a 10 kWp photovoltaic grid-connected system with various system losses. The analysis shows that a total of 15,021 kWh of energy can be injected into the grid from Payra port annually. Over a year, the proposed system performance ratio was predicted to be 91.2%, demonstrating the enormous potential for a solar plant to supply Bangladesh’s rising energy needs in the future.

We propose a linearized cost-effective radio-over fiber (RoF) downlink transmitter architecture for centralized radio access networks (CRANs) based on the near-millimeter wave range. A linearized Mach-Zehnder Modulator (MZM) is employed to reduce the distortion resulting from the detection process of the photodiode. The proposed RoF architecture can be employed as a fronthaul for 5G and beyond networks, where a downlink transmitter architecture that uses Orthogonal Frequency Division Multiplexing (OFDM) and Quadrature Amplitude Modulation (QAM) is employed in a system where the signal processing is centralized at a baseband unit (BBU) rather than at the remote radio heads (RRHs). The outcomes of the simulation show that the suggested linearized CRAN transmitter design is well-suited for 5G and future networks.

The transmission and reflections of incident light have been investigated using novel solar cell construction combining nanoparticles with perovskite. The Transverse Electric (TE) mode for perovskite solar cells with a nanoparticles-glass layer were studied using the Transfer matrix method. The transmittance of the proposed structure for three kinds of nanoparticles doped on the glass cover is studied here. We study the effect of changing volume fraction and glass layer thickness on transmittance. It is obvious that nanoparticles and perovskite can improve transmission while lowering or eliminating reflection, which is critical for optimizing light management in future solar cells.

The diverse of renewable and traditional sources of electrical power generation has been driven the need for Home Energy Management System (HEMS) to control the operation of different sources inside smart homes. In this paper, Hybrid Power Source Controller (HPSC) with the presence of the utility Smart Grid (SG) and the Fuel Cell (FC) is invented to optimally control and share the demands of required load power between SG and FC based on Fuzzy Logic Controller (FLC). The FLC is designed to reduce the electricity price and to maintain the grid stability. Wireless Sensor Network (WSN) is employed to measure the grid frequency, electrical current, and electrical voltage. The inputs to the FLC are the load power and the grid frequency, while the outputs of FLC are the amounts of electrical powers delivered from the SG and FC. Simulation results show that the proposed HPSC can smartly compute the amounts of delivered power from the SG and FC according to the current measurements of grid frequency and load electrical power so that the energy cost and grid stability are improved.

The main objective of this research is to help solve the deficit and decrease the cost of construction raw materials or provide alternatives for cement, which is sand-plastic. Sand-Plastic consists mainly of sand and recycled plastic, in addition to other materials in small traces such as UV stabilizers, cohesive additives, colour pigments, and fillers. The goal is to optimize the mechanical and physical properties of the Sand-Plastic; to optimize the compression strength, flexure strength, abrasion resistance, and water absorption via controlling the mix proportions of plastic to sand and the process parameters. The path taken was to design and manufacture a mould to produce Sand-Plastic samples of different sizes and various mixes. 15, 20, and 25% plastic (Low Density Polyethylene, LDPE) samples have been examined against compression strength and flexural strength for a temperature range of 150 to $300 ^{circ}mathrm{C}$. Tests results indicated that a 20% plastic composition and a temperature between 200 and $250 ^{circ}mathrm{C}$ yields the optimum mechanical and physical properties.
