The impingement of fuel sprays on the piston surface significantly affects mixture formation, combustion performance, and pollutant emissions in Direct-Injection Spark-Ignition (DISI) engines. To better understand the fuel adhesion behavior, the fuel adhesion characteristics of fuel spray impinging on the flat wall under cross-flow condition were investigated in this work. Refractive Index Matching (RIM) were employed to observe the propagation of fuel adhesion. Then the area, mass, and thickness of fuel adhesion were evaluated under various cross-flow velocities. Also, the propagation mechanism and lifetime prediction of fuel adhesion under the cross-flow conditions were revealed. The experimental results can provide necessary guidance on the operating conditions of airflow inside the engine. © 2022 by the Japan Society of mechanical Engineers All rights reserved.

The aim of this study is to investigate the extracted Nypa fruticans as an alternative biomaterial used for 3D printing application in the biomedical and pharmaceutical. An important substances that was extracted from nipa palm fruit is galactomannan, a water-soluble heteropolysaccharide. It was considered to the polysaccharide-based polymer material used to fabricate scaffold tissue by 3D printing approach for medical purposes. Emphasis was placed on the synthesis and characterization of extracted nypa fruticans as the primary material, along with glycerol and sorbitol serving as polimerization agents. Extracted nypa with 3%, 5% and 10% amout of variation glycerol and sorbitol was evaluated. The experimental procedures conducted in the laboratory facilitated the isolation, production, purification, and fabrication of the extracted nypa polymer gels. Various properties of the nypa compounds and chemical composition through Fourier-transform infrared (FTIR) Spectrometry were analyzed. Findings indicated that extracted nypa refer to ether bonds (CH2-O- CH2) observed at 875.04 cm-1, identifying compound is galactomannan. This substance is classified within the polysaccharide category due to the appearance of peaks within the range of 900 to 1200cm-1. The incorporation of different amount percentage of glycerol and sorbitol, resulted in distinct impacts on the geometry of 3D printing scaffold material laying down. © 2024 IEEE.

Magnesium-based batteries are potential candidates for next-generation rechargeable batteries due to the divalent nature of magnesium cations and the natural abundance of magnesium resources. In this study, the electrochemical activity of Mg-6mass%Al-3mass%Ca anodes combined with Sn was investigated. Thin ribbons of the anode specimens were prepared by a single-roll rapid solidification method. The results showed that the electrochemical activity increased upon adding 1 mass% Sn, while it decreased for 3 mass% Sn. Based on the results of an X-ray diffraction analysis, the addition of Sn led to the formation of Mg2Sn and Ca2Sn phases, which increased the lattice distortion. Scanning electron microscopy observations indicated that these secondary phases were homogeneously distributed for 1 mass% Sn addition, while they were coarsely distributed for 3 mass% Sn. © 2025 The Japan Institute of Light Metals.

Temiki (Melastoma Candidum) is one of the unutilized wild plants observed to be turning pests on plantations. It has only been used for medicine and not for engineering purposes. Therefore, this study aims to identify and analyze Temiki’s chemical compounds, which are useful as corrosion inhibitors. The plant was washed, dried, then blended until it became a fine powder, and was further extracted by employing the maceration method with ethanol as solvent. The extracted compounds were also analyzed using Gas Chromatography-Mass Spectrophotometry (GC–MS) and the results obtained include, 2-Furancarboxaldehyde (CAS) Furfural, 1,2,3-Propanetriol (CAS) Glycerol, Acetic acid,1-(2-methyltetrazole-5-yl) etheny, 4H-Pyran-4one,2,3-dihydro-3,5-dihydroxy, 5-Hydroxymethylfurfural, cis-dimethylmorpholine, 3-penten-1-ol,2,2,4-trimethyl-(CAS)2,2,4, 2-AMINO-9-(3,4-DIHYDROXY-5-HYDORO, D-Allose, beta-D-Glucopyranoside, methyl, Hexadecanoic acid, methyl ester, 9,12,15-Octadecatrienoic acid, methyl ester.

Boring bars with a large length-to-diameter (L/D) ratio in the machining process can cause excessive vibration or chatter, which reduces product quality. Dynamic vibration absorber (DVA) is a vibration reduction system that can reduce the chatter effect. In this study, DVA has the shape of a cone placed inside a boring bar, which consists of a mass of absorber made of brass covered with rubber. The rubber is varied, namely natural rubber and neoprene rubber. The simulation is carried out with various cutting parameters, including spindle speed, feed rate, and depth of cut. Based on the simulations, the DVA cone's shape allows it to reduce vibrations in all directions and produce the same reduction values on each axis. Customized boring bar L/D 9 with DVA natural rubber and cutting parameter 2 is the variation with the highest vibration response reduction value, namely 88.50% in the x-axis direction, 83.89% in the y-axis, and 88.52% in the z-axis. Customized boring bar L/D 7 is a geometry variation with the best operation because it can reduce vibration in most variations of cutting parameters compared to other variations of boring bars, namely 23 out of 27 cutting parameters. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In this paper, multi-layer feed forward neural networks are used to predict the chemical exergy, hydrogen mole fraction, carbon monoxide mole fraction, and methane mole fraction during gasification of Brazilian wastes biomasses during gasification in a bubbling fluidized bed reactor. These artificial neural networks (ANNs) with different architectures are trained using the Adam back-propagation algorithm and a cross validation is also performed to ensure that the results generalize to other unseen datasets. A rigorous study is carried out on optimally choosing the number of hidden layers, number of neurons in the hidden layer and activation function in a network. Ten input and four output parameters are used to train and test various neural network architectures in single output prediction paradigms using the available experimental datasets. The model selection procedure is carried out to ascertain the best network architecture in terms of predictive accuracy. The simulation results show that the ANN based methodology is a viable alternative which can be used to predict the performance of a bubbling fluidized bed gasifier. © 2024 37th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy systems, ECOS 2024.

Nowadays, industrial processes are creating increasing demands for optimized and efficient sensing systems and require high reliability and a short time interval for information delivery. This paper presents an embedded sensor system that uses the ESP-NOW protocol with a Mesh and Ad Hoc network, in order to provide an auto mesh configuration upon failure at some point in the network. This system was implemented to monitor the variables of an induction motor, after which, before sending the data to the cloud, local processing is performed to reduce the volume of data. Finally, a computer simulation of the WROOM-32 module is performed for a thermal analysis during its operation, where the heating points of the plate are identified and analyzed, in order to validate that the system, even processing a large amount of data, maintains a high reliability during its operation. ©2023 IEEE.

The electrification of offshore oil and gas platforms (OOGPs), using offshore wind turbines, is now a reality, aimed at minimizing carbon emissions. In this scenario, the utilization of battery energy storage systems (BESS) improves both efficiency and power quality. As this integration comes with a high CAPEX, industries demand exploring BESS for multiple ancillary services on OOGPs. Thus, this paper proposes an alternative approach to energizing a power transformer (PT) using the BESS power conversion system (PCS) on the platform, aiming to minimize inrush currents. This avoids the necessity for additional bulky devices, converters, or dc voltage sources specifically designated for this purpose. The strategy consists of manipulating residual core flux using BESS PCS followed by a controlled switching, which reduces inrush currents during PT energization. The results show effective reduction of the inrush current from 2.31 pu to 0.16 pu for the presented case study. © 2024 IEEE.
