Abstract

Heat transfer in turbulent flows is one of the essential topics in power plants and thermal-based engineering. This study aims to analyze the effects of density changes due to heat transfer in a turbulent environment—which is usually neglected because it can cause instability in a simulation. We simulate an available experimental case of turbulent heat transfer of air with OpenFOAM: one with an incompressible approach (no density change) and another with a compressible treatment. The simulation geometry is a 0.75 × 0.75 m2 square cavity, where its left and right walls are kept at a temperature difference of 40 K. We compare and analyze the temperature, velocity, and turbulence kinetic energy profiles of both simulation results against the experimental data. We found that from all qualitative and quantitative comparisons, the change in density plays a vital role in turbulent heat transfer. The compressible treatment gives better results than the incompressible: the neglection of density change causes a significant difference with the experimental data. Thus, we strongly recommended incorporating compressibility in simulating heat transfer in turbulent flows.

Abstract

This systematic review study aims to determine Moodle e-learning in physics learning in terms of nationally published journals. This type of research is a systematic review study using the Prisma model. The dominant research methodology is quantitative research with descriptive statistical analysis. The findings in this study are that the author of many articles contains Research & Development (R&D) research on physics learning devices, the distribution of authors and institutions is uneven, and the data obtained is in the form of numbers. Data analysis was performed manually and using Vosviewer software. Data analysis that was done manually included: SINTA level, year, author, institution, use of Moodle, keywords, samples based on educational level, type of research, and data analysis in the research of each article. The results of the article review show that the use of Moodle e-learning is more widely used in the development of teaching materials than used in classroom learning experiments. So it can be concluded that the need for learning development by utilizing the Moodle platform so that learning is more meaningful and enjoyable is not only used only for physics learning training.

Abstract

The rapid development of technology greatly affects the education system in Indonesia, especially in the use of Information Technology (IT) devices such as hardware and software in the teaching and learning process. This research focuses on developing interactive e-modules using the Flip PDF Professional application to improve students' quantum physics learning experience. This research problem addresses the difficulties faced by students in understanding quantum physics concepts, which leads to low academic achievement. This study aims to assess the feasibility and user satisfaction of the interactive e-module "History of Quantum Physics" developed with the help of the Flip PDF Professional application. The research method used is ADDIE (Analyse, Design, Development, Implementation, Evaluation) which involves validation by material experts and trials on physics education students at two universities. The results showed that the feasibility of interactive e-modules of quantum physics history by media and material experts obtained results that were feasible to be tested without revision with a percentage of 81.8%. So that the e-module can be tested on undergraduate and postgraduate physics education students. User satisfaction test results show that e-modules can be used as a support for quantum physics learning media with a satisfaction percentage of 91.33% or very satisfied.

Abstract

This study aimed to prove the concept of diffraction by determining the wavelength of green (532 ± 10) nm and purple (405 ± 10) nm laser pointers using transmission diffraction gratings of light interference patterns. The wavelength measurement results are then compared with the wavelength indicated on the laser. In this study, the distance between the grid and the screen (L) was varied by 100 cm, 75 cm, and 50 cm while the distance between the gaps (d) was varied by 100 lines/mm, 300 lines/mm, and 600 lines/mm. The method used in this study is an experimental method using a transmission diffraction grid and the interference results are displayed on the screen. The results showed data on brightspot distances of order n-1, 2, and 3 from the center of the pattern with variations in laser green and purple, variations in screen distance with grids (L) 100 cm, 75 cm, and 100 cm, and variations in gap width (d) 100 lines/mm, 300 lines/mm, and 600 lines/mm. The data is then analyzed using the bright-pattern constructive interference equation to determine the wavelength. Based on wavelength measurement data, at the same lattice distance with the screen (L) and lattice width (d), the green laser has a brighter distance that is farther apart than the purple laser. The conclusion of this study is that when the gap width is smaller, the distance between the brights will be farther apart or the x value is larger, the results of measuring the wavelength are appropriate on the green laser (532 ± 11) nm, and close to the purple laser (412 ± 23).   Keywords: Wavelength, Laser, Transmission grating, Diffraction, Interference.
