The experiments were conducted at engine speeds of 1750 and 2500 rpm. Modeling and optimization were performed using Design-Expert software with the D-optimal method, resulting in 16 experimental runs. The results indicated that iron oxide nanoparticles had a more pronounced effect compared to magnesium oxide nanoparticles. For base gasoline, NOx and HC emissions ranged from 685 to 670 ppm and 113 to 116 ppm, respectively, with increasing engine speed. By adding isopropanol and iron oxide nanoparticles, NOx and HC emissions varied in the ranges of 159–335 ppm and 124–65 ppm, respectively.

This study addresses the optimization of solar collectors to maintain a constant outlet temperature of 50°C, a key requirement for residential and industrial applications. A simplified model based on energy equations was developed, coupled with computational fluid dynamics analysis, to derive design-ready formulas for collector size and fluid mass flow rate. The research integrates numerical modeling and predictive frameworks, bridging gaps between theoretical and experimental approaches prevalent in prior studies. Key findings reveal an optimal collector length range of 0.537–0.539 m, with mass flow rates scaling proportionally to solar intensity (peaking at 1.049 kg/h at 1000 W/m2). The Nusselt number reached 124.46 under high radiation, confirming enhanced convective heat transfer, outperforming conventional designs by 12%. The novelty of this work lies in its dual theoretical-practical approach, offering actionable insights for industrial design while advancing scalable solar thermal solutions. These results not only provide a robust tool for solar collector optimization but also contribute to global sustainable energy goals by improving the efficiency and applicability of solar thermal systems.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relative conversion to oxirane (RCO) was used to evaluate efficiency. Three catalysts were tested: sulfuric acid, amberlite IR 120, and zeolite. Kinetic modeling was conducted using the ODE45 solver based on the Runge Kutta method, showing good agreement with experimental data. Optimum catalyst loadings were 1.0 g sulfuric acid (45% RCO), 2.0 g amberlite IR 120 (75% RCO), and 1.0 g zeolite (44% RCO).

Against the backdrop of increasing alarm on climate change, air quality pollution, and energy resources sustainability, it is now imperative to understand their collective impact on tourism. The adoption of green energy, environmental pollution, and tourist arrivals are interrelated in this study, centering on China's dynamic tourism environment. Spanning from 1975 to 2022, the study employs the Generalized Method of Moments (GMM) estimator for parameter estimates. The findings reveal a negative relationship between international visitor arrivals and factors such as renewable energy consumption, economic development, and transit services. Conversely, the average temperature emerges as a significant factor that positively influences the potential for international tourism. Granger causality estimates support several hypotheses, including the notion that tourism drives carbon emissions and economic development, tourism propels transport services, renewable energy fuels economic growth, emissions drive economic growth, and temperature influences emissions within a nation. The results can foster the development of environmentally conscious and economically resilient tourist sectors.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar stills for desalination is a renewable and cost effective method of producing fresh water from sea water. This study presents a dynamic numerical analysis of a pyramid-shaped solar still integrated with phase change material (PCM), using a transient MATLAB model. The model also uses a 2D finite difference approach to simulate the heat conduction process of PCM and air zones to predict the temperature field in the domain. The latent heat effect is modeled by enthalpy method, which can help to predict the phase change behavior of the PCM. MATLAB was used to build the full numerical model, which includes the empirical correlations, the experimental parameters, and the transient input data of solar radiation and ambient temperature for an hour-by-hour basis for 24 h. This involves a one-dimensional transient heat and mass transfer analysis of the solar radiation, basin water, glass cover, ambient air, and the PCM layer. The fin enhanced PCM (FPCMs) configuration at 2 cm depth achieved the highest cumulative distillation (7.3 kg/m2), confirming the advantage of combining thermal storage and extended heat transfer surfaces. Simulation results are the time dependent temperature of water, the temperature of the glass cover and PCM, hourly efficiency, evaporative heat losses and the distillate output for a day.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146136727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this investigation, a new hybrid thermal heat sink consisting of phase change material with different arrangements and mass flow rates has been used for cooling an Insulated-gate bipolar transistor. As an innovation, to reduce the operating temperature of the power module at a heat flux of 100 W/cm2, paraffin and metal-based PCM have been applied in the water cooling chamber and simulated simultaneously. The finite volume method and piezo algorithm were used to solve the governing equations. The melting process of the PCM was simulated by the enthalpy-porosity method in a three-dimensional domain. The comparison of local temperature distribution among four models (A–D) shows that Case D reduced the operating temperature by about 15% versus other arrangements, and at flow rates of 0.0025–0.005 kg/s achieved up to 3°C lower than pure fluid. For paraffin (k = 0.12 W/m·K, L = 255,000 J/kg), Fo·Ste. at 3600 s is 0.0904, while for the metal alloy (k = 33.2 W/m·K, L = 202,000 J/kg) it is 6.5052, indicating much faster melting. The metal-based PCM, with higher conductivity and lower latent heat, enhances heat transfer and rapid cooling, whereas paraffin, with slower melting, suits long-term energy storage.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146130199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
