Numerical Study of Three-Dimensional Models of Single- and Two-Phase Nanofluid Flow through Corrugated Channels
No full textThis study delves into computational fluid dynamics (CFDs) predictions for SiO2–water nanofluids, meticulously examining both single-phase and two-phase models. Employing the finite volume approach, we tackled the three-dimensional partial differential equations governing the
turbulent mixed convection flow in a horizontally corrugated channel with uniform heat flux. The study encompasses two nanoparticle volume concentrations and five Reynolds numbers (10,000, 15,000, 20,000, 25,000, and 30,000) to unravel these intricate dynamics. Despite previous research on the mixed convection of nanofluids using both single-phase and two-phase models, our work stands out as the inaugural systematic comparison of their predictions for turbulent mixed convection flow through this corrugated channel, considering the influences of temperature-dependent properties and hydrodynamic characteristics. The results reveal distinct variations in thermal fields between the
two-phase and single-phase models, with negligible differences in hydrodynamic fields. Notably, the forecasts generated by three two-phase models—Volume of Fluid (VOF), Eulerian Mixture Model (EMM), and Eulerian Eulerian Model (EEM)—demonstrate remarkable similarity in the average Nusselt number, which are 24% higher than the single-phase model (SPM). For low nanoparticle volume fractions, the average Nusselt number predicted by the two-phase models closely aligns with that of the single-phase model. However, as the volume fraction increases, differences emerge, especially at higher Reynolds numbers. In other words, as the volume fraction of the nanoparticles
increases, the nanofluid flow becomes a multi-phase problem, as depicted by the findings of this study
Comparison of transfer process layout at company a using arena simulation software
Full text linkThis study aims to analyze, provide ideas and compare two processes of transporting oil palm fruits from plantations to factories, namely through the use of roads and cableway systems. This study was conducted at Bukit Pasir Palm Oil Mill Sdn. Bhd. Which is a small-scale palm oil production company located in Bukit Pasir, Muar, Johor, the storage size for palm fruit processing at the factory involved is as much as 50 metric tons/hour where the final product for the palm fruit is divided into two, namely crude palm oil and kernel. Among the problems faced is the lack of information on the appropriate way to increase productivity for a factory. This study was done by focusing on the layout of the palm fruit transfer process from the farm to the factory. Using Arena simulation, the results show a comparison of the performance between the two processes. The road approach shows more travel time compared to the use of the cableway because it involves a long journey and involves high road construction costs. Meanwhile, the cableway system shows the potential to reduce construction costs where the difference in construction costs is as much as RM 5754.84 while in terms of time it involves fast and little travel time compared to road use with a reduction of 5.89%. The results of the analysis show that the choice between these two processes requires careful weighing between the time and cost factors. The recomendation that can be given by propose the idea to a large-scale companies or a company that will be built in future where the impact of introducing innovations such as cableways for the transport process may provide benefits in the long term, including cost reduction and increased operational efficienc
Al:Cu2O n‑Type Semiconductors�Electrochemical Fabrication of Heterojunction and Homojunction Photovoltaic Devices
Full text linkN-type Al:Cu2O semiconductor layers were prepared via cathodic electrodepositions from a copper(II)-lactate
complex aqueous solution with added aluminum chloride.
Subsequently, the Al:Cu2O/n-ZnO heterojunction and p-Cu2O/ n-Al:Cu2O homojunction photovoltaic devices were constructed by using sequential electrodeposition. The effects of Al impurity were investigated by examining the structural, optical, and semiconductor characteristics of the Cu2O layer using XRD, FE-SEM, XPS, and UV−vis analyses and electrochemical measurements of Mott−Schottky plots. Photovoltaic characteristics were then assessed through current density−voltage curves under AM 1.5G illumination and external quantum efficiency (EQE) for both Cu2O/ZnO heterojunction and p-Cu2O/n-Al:Cu2O homojunction devices. The introduction of Al impurities induced a change in the semiconductor type from intrinsic p-type Cu2O to n-type and
decreased carrier concentration while keeping the characteristic cubic lattice. A slight increase in the band gap energy of the Cu2O layers from 2.00 to 2.08 eV was noted with an increase in Al impurity content. The maximum value of the EQE evaluated for the heterojunction photovoltaic devices composed of Cu2O, Al:Cu2O, and n-ZnO semiconductor layers decreased with an increase in Al
impurity content. However, the EQE at wavelengths ranging from approximately 630 to 500 nm was enhanced by Al impurity introduction, although the optical absorption characteristics were almost the same in absorption coefficient and dependence on the wavelength, irrespective of the Al content. The enhancement was attributed to an increase in internal quantum efficiency originating from the accelerating dissociation of excitons to free carrier generation for the yellow and green exciton series due to the introduced
Al impurities. An EQE of 28% was achieved in the p-Cu2O/n-Al:Cu2O homojunction photovoltaic device, along with enhancements in the EQE values at wavelengths ranging from 630 to 500 nm, showing that both the p-Cu2O and n-Al:Cu2O layers functioned as photovoltaic layers, as evidenced by their external quantum efficiency feature

Factors Influencing Teachers’ Quality in Teaching and Learning at School Based on the Elements of SKPM Quality@School Standard 4: A Systematic Literature Review (SLR)
No full textThe quality of teachers is the central pillar in the development of students in schools. In addition, the quality of teachers in various aspects can ensure that the quality of teaching and learning aligns with current developments. However, sometimes, teachers need to be more sensitive to the guidelines provided to shape the quality of teaching and learning in schools. Moreover, some teachers must be made aware of the current changes in the national education system. Guidelines for generating quality teachers in terms of learning and facilitation aspects have been introduced by the Ministry of Education Malaysia (KPM). However, the need for more awareness in implementing the elements of SKPM Quality @ School Standard 4 raises deep concerns about the quality of teaching and learning by teachers in schools, which are expected to meet the aspirations of the national education system in the future. Therefore, this study examines the factors influencing teachers’ quality in teaching and learning at school based on the elements of SKPM Quality@School Standard in various types of
schools. This qualitative study uses a descriptive design. Data was collected through document analysis from journals, articles, proceedings, and theses. Data were analyzed using thematic analysis. The findings of the study indicate that five main factors influence teachers’ quality in teaching and learning based on the elements of SKPM Quality@School Standard 4 elements in various schools. Moreover, this study is still a hot topic of discussion. It requires more in-depth examination because there are still gaps in applying the SKPM Quality @ School Standard 4 elements among school teachers. Therefore, understanding and delving into these elements can produce quality teachers in Teaching and Learning to provide the best education on par with other countries. This aligns with the Ministry of Education Malaysia's Strategic Plan (PSKPM) 2024-2030, based on Strategic Core 1, aimed at improving access and quality of education in Malaysia. Hopefully, this study can provide a valuable impact on all scholars, especially teachers, in collectively shaping knowledgeable and informed
children starting from primary school
Effect of V-shaped Side Groove on Shear Lips Formation of Aluminium Alloy 6061 by Charpy Impact Test
No full textThis study investigates the effect of V-shaped side grooves on shear lip formation in aluminium alloy 6061 through Charpy impact testing. Aluminium is used in machines and industry as a structural component due to its mechanical properties, lightweight characteristics, easy fabrication, and high specific strength. The presence of a V-shaped
side groove alters the stress distribution during impact, potentially influencing the deformation behaviour and fracture characteristics of the material. In this work, the
impact tests were conducted on specimens with and without a V-shaped side groove, and the resulting shear lips formation was analysed. The findings reveal that the Vshaped side groove minimisesshear lip formation compared to specimens without side grooves. This can be attributed to the surface morphology, which shows a lesser shear lip area with an increasing side groove depth ratio. A smaller shear lips area in Charpy impact tests signifies reduced plastic deformation near the groove or notch region. It indicates the material’s fracture characteristic has lower ductility and limited ability to deform plastically before a fracture occurs. This implies decreased energy absorption capacity, equated to impact energy, and an increased likelihood of brittle fracture behaviour as the side groove depth ratio increases. The micrograph of the fracture surface shows dimples, shear, and cleavage patterns
