Abstract In the present work, numerical investigations are conducted with 22 % cut segmental baffle heat exchanger (SB), 20°, 30°, and 40° helical baffles shell and tube heat exchangers (STHX) to estimate the overall heat transfer coefficient (OHTC), pressure drop (PD) and friction factor. Among the studied heat exchangers (HE), 40° helical baffles STHX provided the highest OHTC with minimum pressure drop. Hence, further investigations are conducted experimentally with 40° helical baffles STHX. OHTC increased by 2.65 % for 20° helical baffles, 5.37 % for 30° helical baffles, 9.78 % for 40° helical baffles when compared with 22 % cut segmental baffle heat exchanger. The deviation between experimental and numerical OHTC is 2.64 % 40° helical baffles.

Abstract The development of renewable energy-based applications is nowadays a forced demand of society, for chasing the target set by the governments and the concerned organizations, to reduce or limit the carbon penetration in the environment. Sincere efforts are being made by academics and researchers to create applications based on renewable energy that are reliable and efficient. Green revolutions increase agricultural fields and alter grain production rates, but they also increase energy consumption since agricultural machinery is used more efficiently, mostly for irrigation needs. The purpose of this work is to introduce a hybrid renewable energy system (HRES) that can take the place of the diesel pump often used for time-bound crop irrigation. This HRES system consists of a photovoltaic generator as the main power source supported by a battery energy storage system. For this hybrid system, the development of a Proportional & Integral (PI)-based integrated hybrid controller is proposed to regulate the charge/discharge cycle of the battery energy with maintaining the load demand simultaneously. Controlling of this hybrid system is carried out in the LabVIEW environment.

Abstract In order to effectively monitor transmission lines and transmission towers, a number of different types of sensors are needed. A lot of times, these sensors along with the transmission lines and transmission towers are in inaccessible or hard-to-access areas and replacing their batteries is difficult. Yet they need consistent power supply. By harvesting energy directly from these medium and high voltage power lines, these devices can become self-sustaining while the overall system is more friendly to the environment. This paper presents a novel approach to high energy harvesting based on capacitive coupling between the power line and the harvesting line. This technique has several advantages, namely high output voltage, easy adjustment of coupling coefficient, and low cost. The validation and implantation of this harvesting system are proposed with the support of experimental results. This energy-harvesting ability of W and mA levels is achieved for the power line monitoring devices, with higher power output depending on the length and the size of the harvesting line.

Abstract In addition to traditional piezoelectric polymers, mono-crystals and ceramics, piezoelectrets or charged voided polymers have shown an interesting piezoelectric response by converting the mechanical energy into electrical and vice versa, therefore being incorporated in a number of advanced electromechanical transducers. This article is a review on the different phases for the elaboration of pseudo piezoelectric films based on passive polymers. First, several methods for the elaboration of the cellular structure of these materials are explained in the main text, with the morphological representation of the reached porosity. The porosity represents a cell to embed the positive and negative electrical charges created by the most common electrical charging processes, which are subsequently mentioned. Different theoretical models are emphasized as well to predict the piezoelectric behavior of this porous polymers. Finally, some of the latest harvesting energy applications based on porous polymers are collected. All the considerations cited above make Piezoelectric porous polymers open access materials that can be developed and optimized by the control of the porosity then used in energy harvesting applications.

Abstract The expanding need for electricity has stimulated research and development of novel supply sources for energy production, conversion, and storage. Many studies are being done to increase the effectiveness of conversion systems as renewable energy is integrated into power networks on a larger scale. The global challenge is to minimize manufacturing costs and increase the use of sustainable resources. In this sense, photovoltaics is viewed as a particularly promising source due to the low cost of implementation and the wide range of applications it could be used for. This research focuses on the analysis, modeling, and simulation of a smart controller for a step-up converter that uses an artificial neural network (ANN) as a maximum power point tracking (MPPT) technique to provide maximum power. The proposed ANN-based algorithm is performed in Matlab/Simulink software, and its effectiveness has been demonstrated under varying climatic conditions.

Abstract Computation of transmission system efficiency of electromagnetic radiation becomes inaccurate when Friis formula is used in Fresnel zone (near-field zone) of wireless power transmission (WPT). A novel methodology has been proposed in this paper for estimation of the power density, received power and transmission system efficiency at a particular operating frequency in the near-field zone. The power transfer and transmission system efficiency need to be maximized for minimal dimensions of transmitter and receiver. Utilization of negative refractive index metamaterials (MM) between transmitter and receiver is proposed to achieve maximum power transfer. In the present paper, variation of received power and system efficiency with respect to transmitting distance is computed and compared for WPT system with and without metamaterials. The variation of system efficiency is studied for varied location of metamaterial from transmitter by assuming metamaterial diameter at a given location is greater than or equal to the beam diameter at that location. Different configurations with varied input power and transmitting distances from shorter to longer range are considered in the study to analyse parameters that affect system efficiency. The approach for identifying optimal number of metamaterials and their placement between transmitter and receiver for maximum power transfer has also been discussed.

Abstract Clean sustainable energy and proper utilization of the available natural resources are of paramount importance for the modern societies. In this work, green composite materials were designed, fabricated and utilized as back sheets for the solar photovoltaic panels to investigate their effects on the output voltage of the solar cell unit. Such replacement of the back sheet of the solar cells would improve their efficiency while reducing the cost and enhancing better environmental conservations. Green back sheet composites were designed with 25 wt% and 50 wt% of high-density polyethylene with all Rhus typhina, Punica granatum and Piper nigrum powders. Investigations of the effect of green composite back sheet materials on solar panel output voltage harvesting have been carried out in Jordan at Zarqa city (latitude 32.07°, longitude 36.08°). Results have revealed that R. typhina and P. nigrum based composites with 25 wt% fiber loading have demonstrated much better output voltage comparable to the original back sheet cell. The maximum output voltage was found to be enhanced about 58 % with the green composite back sheets. This in order would improve the efficiency of such solar cell units and enhance better environmental indices.

Abstract This paper presents a new approach to improve the performance of Zeta converters, which are commonly used in cost-sensitive circuits to manage unregulated power supply. The converters are designed to produce positive output voltages based on input voltages, and they use a buck controller to power a PMOS-based FET for high-side control. Compared to other converters, such as SEPIC, Zeta converters are smaller and more scalable for micro applications due to the use of coupled inductor circuits. The performance of Zeta converters is heavily influenced by the ratings of their passive components. To optimize component rating choices, researchers have developed several pattern analysis models. However, these models often require context-specific ratings and lack a parameter selection method for continual reconfigurations, making them difficult to deploy in practice for different use cases. To address these limitations, the authors propose a hybrid soft computing methodology for passive component selection in multiple load Zeta converters. The proposed approach combines Particle Swarm Optimization (PSO) to determine initial component ratings and Grey Wolf Optimization (GWO) to improve conversion efficiency, output gain, and Total Harmonic Distortion (THD). This is achieved by modeling a fitness function that incorporates output metrics and optimizes them incrementally for real-time deployments. The results show that the suggested methodology can reduce THD by 6.5 %, increase conversion efficiency by 3.4 %, and maintain a gain improvement of 1.5 % across numerous use cases. These improvements make the model suitable for real-time use applications. Overall, the proposed approach provides a promising solution to the challenges of passive component selection in Zeta converters, which can lead to more efficient and cost-effective power management in various circuits.

Abstract In order to improve the practical effect of the power environmental protection platform, this paper combines the big data technology to develop and design the power environmental protection platform. In this paper, a power factor correction (PFC) and resonant half-bridge joint controller is used to combine the traditional two-level topology into one-level topology. Moreover, this paper adopts a fixed frequency half-bridge LLC resonant converter with a simple control circuit to obtain a stable resonant half-bridge controller with a fixed output voltage. The choice of this overall power topology architecture can not only meet the design requirements, save costs and simplify the control of the circuit, but also improve the efficiency of the whole machine and the performance of the power environmental protection platform. The experimental research shows that the power environmental protection platform based on big data proposed in this paper can effectively improve the effectiveness of power environmental protection strategies.
