Although many alternative fuels currently have enhanced performance characteristics, continuous research attempts to further enhance their quality even more. This research focuses on improving fuel quality by incorporating Waste vegetable oil biodiesel derived from Liza oil and Butylated Hydroxytoluene (BHT). The combination of these factors results in a novel approach that uses experimental and parametric optimization to outperform current constraints in alternative fuels. The objective of this study is to compare the performance and emission characteristics of several blends of diesel, including B10 (20% biodiesel + 500 ppm BHT + diesel), B20 (20% biodiesel + 1000 ppm BHT + diesel), B30 (20% biodiesel + 1500 ppm BHT + diesel), B40 (20% biodiesel + 2000 ppm BHT + diesel), and B50 (20% biodiesel + 2500 ppm BHT + diesel). The tests were carried out at a variety of engine loads and speeds. The performance of Liza oil blends, as assessed by engine performance and emissions characteristics, was found to be comparable to that of diesel. Mechanical and brake thermal efficiency was determined to be highest for the B30 and B40 mixtures. The Liza oil Biodiesel operation exhibited fewer hydrocarbon emissions than the diesel fuel mode at B20. The D-optimal design was utilized for the experiment design. The data collected was used for the analysis of variance (ANOVA) for the development of mathematical expression for each response variable. The response surface methodology (RSM) was employed for the development of response surfaces to explore the effects of control factors on each response variable. The most favorable results were obtained using desirability-based optimization at 8.22 kg engine load and 500 ppm BTH concentration. It resulted in 20.04% brake thermal efficiency, 0.4 kg/ kWh brake specific fuel consumption, 39% mechanical efficiency, 0.028 Vol.% carbon mono-oxide, 7.39% carbon-di-oxide, 39.16 ppm hydrocarbon, and 1230 ppm nitrogen oxide as response variables.","PeriodicalId":11580,"journal":{"name":"Energy Sources, Part A: Recovery, Utilization, and Environmental Effects","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the benefit of an East-West (EW) reflector and coal cinder additive (CC) to improve the exergy efficiency in the inner zones of a salt gradient solar trapezoidal pond. Additionally, it presents a temperature distribution model for solar ponds. In this study, we designed, constructed, and analyzed salt gradient trapezoidal solar ponds, evaluating them from an exergy perspective and comparing them to conventional trapezoidal systems. Our findings reveal that the implementation of a double glass cover led to a substantial increase in the average temperature of the heat storage zone, registering a 10.12% boost for the conventional trapezoidal system and a 12.31% enhancement for the trapezoidal system with East-West reflectors. Moreover, the average energy and exergy efficiencies of the lower convection zone for the conventional trapezoidal systems were determined to be 9.2% and 0.5%, respectively, while for the trapezoidal system with coal cinder additives and east-west reflectors, these values were notably higher, at 15.4%, and 0.94%, respectively.KEYWORDS: Coal cinderEast-West reflectorsolar pondenergy efficiencyexergy efficiency Nomenclature A=Upper layer surface area(m2)AS=Sunny area(m2)AS=Shaded area(m2)C=Specific heat capacity(kJ/kg-K)h=Portion of solar radiation conducted (W/m2)I=Incident solar radiation(W/m2)R=Coefficient of reflectionQs=Solar radiation reaching each zone(W/m2)Qc=Heat transfer through conduction(W/m2)T=Temperature (°C)t=Time (minutes)x=Pond layer thickness (mm)Abbreviations=bp=bare pondcin=cinderref=reflectorsol=solutionGreek symbols=θi=Angle of incidenceθrf=Angle of refractionδ=Declination angleρ=Density (kg/m3)η=Efficiencyα=Elevation angleθh=Hour angleθ=Reflector tilt angleφ=LatitudeDisclosure statementNo potential conflict of interest was reported by the authors.Supplemental dataSupplemental data for this article can be accessed online at https://doi.org/10.1080/15567036.2023.2268568.Additional informationNotes on contributorsVinoth Kumar JayakumarVinoth Kumar Jayakumar Assistant Professor, Bannari Amman Institute of Technology, Sathyamangalam Vinoth Kumar J is an Assistant Professor at Bannari Amman Institute of Technology in Sathyamangalam, specializing in the field of solar energy.

While most of earlier studies considered the steady state kind of solar radiation, this study is based on the assumption of the diffuse and erratic nature of solar energy in calculating the sizing rating of SCPP. Moreover, the use of uncertainties in solar radiations is time-consuming and difficult, and hence a theoretical approach is used to get the required results. Statistics and probability theory concerning solar radiation and weather data of Mumbai, India region are used for said analysis. The best generator rating and daily energy output are determined by taking into consideration variables like chimney height, collector radius, and storage thickness below the absorber plate of SCPP. Based on the aforementioned characteristics, one may construct SCPP sizing curves to yield 136, 435, and 945 kWh energy generation in 24 h period. It is essential to consider the full load and part load operations of the generator in order to prevent the unused kinetic energy linked to low velocity and increased velocity. While the majority of the past research by various researchers was carried out under full-load conditions, this study also addresses half-load situations. The current effort will help manufacturers and the scientific community develop sizing and rating taking into account different sun radiation statistics.KEYWORDS: Solar chimney power plantperformance analysissizing and ratinguncertainitysolar radiationpart load operations Nomenclatures ∆p=Pressure drop (Pa)Achim=Cross-sectional area of the chimney (m2)Acoll=Collector area (m2)Cp,water=Specific heat of the storage medium (J/kg-K)D=Chimney diameter (m)g=Acceleration due to gravity (m/s2)H=Chimney height (m)hr=Radiative heat transfer coefficients (W/m2/K)hsf=Convective heat transfer coefficients from storage to fluid (W/m2-K)Ib=Beam radiations (kWh/m2-h)Id=Diffuse radiations (kWh/m2-h)Mw=Mass of the storage medium (kg)Praed=Rated Power(kW)Protor=Power produced by rotor (kW)rb=Tilt factor w.r.t to beam radiationsrd=Tilt factor w.r.t to diffuse radiationsrr=Tilt factor w.r.t to reflected radiationsS=Incident solar flux (W/m2)Ta=Ambient temp (°C)Tcm=Mean temperature of the glass cover(°C)Tfm=Mean temperature of fluid medium(°C)Tg=Mean temperature of the ground(°C)Tsm=Mean temperature of storage medium(°C)Ub=Heat loss coefficients of bottom surface (W/m2/K).Ut=Heat loss coefficients of top surface (W/m2/K)Vchim,in=Velocity of air at chimney inlet (m/s)α=Absorptivity of storage materialβ=Tilt angle (°)ϵc=Emissivity of cover plateϵs=Emissivity of storage top plateηg=Generator efficiencyρchim,in=Density of air at chimney inlet (kg/m3)τ=Transmissivity of the cover plateDisclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsBiren K.

Multi-walled carbon nanotubes (MWCNT) and silicon dioxide (SiO2) nanoparticles were added at weight concentrations of 0.1%, 0.2%, 0.3%, and 0.4%, with two different flow rates tested. Sodium dodecyl sulfate (SDS) surfactant was used to prevent the nanoparticles from agglomerating. After visually observing the hybrid nanocoolant, it was found that SDS as a surfactant prevented sedimentation and maintained stability for two weeks. Furthermore, STEM imaging demonstrated that spherical SiO2 particles evenly distributed throughout the tube-shaped CNTs improved the fluid’s thermophysical properties regarding heat transfer. Heat transfer improvements were assessed with water experiments. The findings indicate that greater nanoparticle weight concentration promotes heat transfer. The most significant improvement in thermal conductance (UxA) was recorded as 28% in the case of 0.4 wt.% MWCNT water-based nanofluid at 0.034 kg/s flow rate as against water.

In this study, the influence of different sizes and densities of particles on coal wettability was conducted, respectively. For this purpose, the coal compositions were explored via XRF and the wetting rising velocity experiment of each coal composition was investigated based on the capillary force. The contact angle decreases obviously with the decrease in particle size. The contact angle decreases as the coal particle density increases. The larger the contact angle, the worse the wettability. The coal compositions had a significant effect on the coal-wetting behavior. The content of organic substances decreased with the decrease in powder size. SiO2 had the highest content and the lowest contact angle among the inorganic oxygen-containing. Hydrogen bonds were created between the hydrogen and oxygen atoms on the surface. The stronger the hydrogen bonding force, the more tightly the water molecules adsorbed. Furthermore, the organic content decreased as the coal density increased. The increase in contaminants could be responsible for this phenomenon. The predictive wetting model between the coal compositions and the contact angle was established and its accuracy was evaluated. The predictive model is reliable at larger coal sizes and lower densities due to an average error at 7.2% of 0.35 mm and 10.61% of 1.35 g/cm3. The results provide some valuable insight into the efficient clean utilization of technology and pre-flotation feedback for coal processing.KEYWORDS: Mineral compositioncontact angleparticle sizedensitywettability model AcknowledgementsThe authors gratefully acknowledge the Scientific Research Foundation for High-level Talents of Anhui University of Science and Technology (Grant No. 2021yjrc57 and 2022yjrc112), Anhui Province University Natural Science Research Major Project (Grant No. KJ2021ZD0046), Anhui Province Key Research and Development Program (Grant No. 2022n07020001), Open Foundation of Institute of Environment-Friendly Materials and Occupational Health (Grant No. ALW2021YF13), Open Foundation of the State Key Laboratory of Mineral Response and Disaster Prevention and Control in Deep Coal Mines (Grant No. SKLMRDPC20ZZ03), Natural Science Foundation of China (Grant No. 52074014 and No. 52104242), China Postdoctoral Science Foundation (Grant No. 2019M662134), and Postdoctoral Science Foundation of Anhui Province (Grant No. 2019B330) for supporting this work.Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Additional informationFundingThis work was supported by the China Postdoctoral Science Foundation [Grant No. 2019M662134]; Open Foundation of State Key Laboratory of Mineral Response and Disaster Prevention and Control in Deep Coal Mines [Grant No","PeriodicalId":11580,"journal":{"name":"Energy Sources, Part A: Recovery, Utilization, and Environmental Effects","volume":"292 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135949808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
