However, its primary drawback is the limited freshwater output. To address this challenge, this study aims to enhance the performance of solar desalination by numerically investigating the application of a porous foam gradient across different absorber geometries. The research examines the impact of various factors, including absorber surface temperature, glass cover temperature, glass slope, absorber and glass geometries, porous medium, and foam gradient, on the system's energy and exergy efficiencies. A detailed analysis was conducted to evaluate the system's efficiency concerning absorber plate thickness, absorber temperature, and glass temperature. The Taguchi optimization method was employed to determine the optimal configuration. Among the investigated geometries, the solar desalination unit with a spherical glass cover demonstrated the highest efficiency. The incorporation of a porous layer significantly enhanced the system's energy efficiency. The increase in productivity was found to depend on factors such as porous layer thickness, porosity, permeability, and the thermal conductivity ratio of the solid to the fluid within the porous layer. The application of a porous layer with variable porosity in different spatial directions resulted in an efficiency improvement of up to 350 % for the P2 case. Furthermore, a minimal difference of only 2.1 % was observed between the Taguchi-based predictions and the CFD simulation results.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"252 ","pages":"Article 123529"},"PeriodicalIF":9.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pyrolysis characteristics, product yield, and bio-oil components of catalytic co-pyrolysis were analyzed.

This study systematically examined the influence of reaction conditions on the DT process, evaluating their effects on the surface morphology and elemental composition of the resulting biochar. This process encompassed a temperature range of 210–300 °C and reaction durations spanning from 15 to 60 min. Optimal conditions for liquid product selectivity were identified, achieving 67.7 % selectivity for LGO at 270 °C after 15 min and 32.6 % selectivity for DGP at 240 °C after 30 min. The highest yields were obtained at 300 °C after 60 min, reaching 10.5 % for LGO and 8.5 % for DGP. Various properties of the obtained biochar were thoroughly assessed, including the higher heating value (HHV), decarbonization, dehydrogenation, deoxygenation, enhancement factor, surface area, pore diameter, as well as solid, carbon, hydrogen, and energy yields. The highest carbon content, reaching 65.3 %, was achieved at 300 °C after 60 min of treatment, resulting in an HHV of 25.6 MJ/kg and an enhancement factor of 1.33.

However, the complex internal flow structures, particularly the wake phenomena and associated flow energy losses (FEL), remain poorly understood, limiting further optimization of PAT systems. The objective of this study is to investigate the wake structure and its correlation with the flow energy loss in a PAT operating in turbine mode. The investigation employs the detached Eddy Simulation (DDES) numerical approach to simulate the unsteady 3-D internal flow within the PAT in turbine mode. The findings showed three locations of the wake structure inside the current PAT: downstream of the stator blades, the runner's splitter blades, and the runner's main blades. The splitter wake region displays the highest flow velocity reduction at approximately 67 %, followed by the stator (65 %) and the runner main blade wake region (62 %). Additionally, the FEL values are highest at the splitter wake region (20), then the stator (19), and the runner main blade (11) at the best efficiency point. The profile of the relative velocity has a contrary relationship with the FEL pattern, as it is found that the FEL increases while the velocity coefficient decreases in all wake regions. Moreover, the high FEL and velocity gradient in the wake region collectively contribute to unsteady shedding and interaction processes, ultimately leading to FEL and reducing the turbine's performance.

By actively or passively integrating phase change material (PCM) walls, the challenges posed by intermittent and unstable energy supply can be effectively addressed. However, conventional single-layer PCM walls typically have only one phase-change temperature, making them effective for only a specific season (i.e., summer or winter), which limits their annual energy efficiency. This study proposes a dual-effect shape-stabilized PCM (D-SSPCM) slab, which is developed by uniformly mixing two types of shape-stabilized PCMs with different phase-change temperatures. This D-SSPCM slab may possess both high and low phase-change temperatures adapting for the environmental characteristics of both summer and winter. To investigate its thermal characteristics, the D-SSPCM was developed first. Then, it was molded into slab and the dynamic thermal characteristics of the melting and solidification processes were tested under specified boundary conditions. The numerical model was validated by experimental results, and the thermal performance of the D-SSPCM wall was analyzed using the simulations. The results indicate that the D-SSPCM slab exhibits two phase-change intervals during both melting and solidification processes. The melting process occurs at 23.6–27.5 °C and 29.1–30.2 °C, while the solidification process occurs at 22.3–24.9 °C and 26.9–30.2 °C.

Recently, more emphasis has been placed on the control execution capabilities of PTOs. The active mechanical motion rectifier (AMMR) is such a design that balances efficiency and controllability. However, the intrinsic nonlinearity brought by switching of its active clutches makes it difficult to evaluate the optimal power the PTO can achieve. This paper introduces a power evaluation method that can approximate the optimal power within tractable time. A larger control space is explored by making the control state-independent as a polynomial function of time. Periodical states are solved analytically under a symmetric switching scheme, leading to an analytical expression of the power in terms of the polynomial coefficients, which significantly speeds up the optimization process. This new method also enables the direct evaluation of electrical power output based on a linear modelling of the PTO drivetrain and the generator. A complete WEC model including an oscillating surge flap, the AMMR PTO, and a generator with a controllable load is represented as an equivalent circuit to analyze various mechanical and electrical responses of the device under regular waves. Particle swarm optimization is employed to find the optimal polynomial coefficients leading to the upper bound power potential. It is found that for the flap structure, an AMMR PTO increases electrical power by 10–30 % over a conventional PTO near the resonance period, where motion rectification is the most beneficial. Hardware-in-loop tests were performed on a small-scale PTO prototype, with damping control of the generator. Experimental results show 10–120 % power enhancement compared to a conventional mechanical PTO.

LE erosion is commonly widespread across a wind turbine blade and is monitored using drone inspection with manual review of images, which is time-consuming due to the large number of images generated. In addition, it is hard to forecast the evolution of a LE erosion defect, and to make prioritization of damages across a fleet of wind turbines.

The method, based on the Bayesian updating method, can capture complex interactions in the degradation process. The physics-based approach can reflect physical degradation mechanisms. Fusion of knowledge from physics-based predictive models with information mined from failure databases using Bayesian updating can combine advantages of the two methods, and also make full use of available knowledge.
