This paper uses different RANS/LES turbulence models to conduct numerical simulation research on the bulb tubular pump model device, specifically focusing on the differences in internal flow characteristics under the small flow stall condition 0.5<i>Q</i>_des and the design condition 1.0<i>Q</i>_des. The macroscopic energy characteristics of different turbulence models are verified through experiment tests, revealing that the DDES turbulence model provides better predicted hydraulic performance under stall conditions. The numerical difference under low flow conditions is mainly due to the different degrees of turbulent flow field analysis, while the analysis degree of high-efficiency flow rate conditions with uniform internal flow remains similar. The vortex identification method Omega is used to visualize the vortex structure characteristics of the time-averaged flow field, uncovering large-scale stall vortex structures under small flow conditions, with the blending RANS/LES turbulence model offering superior resolution of vortex structures. Furthermore, the paper deduces the calculation method of the RANS/LES turbulence model pulsation entropy production based on the SST turbulence model pulsation entropy production calculation formula. A comprehensive investigation of the local power loss characteristics of the main flow-passing components—impeller, diffuser, and bulb—reveals that the blades and wall surfaces are the main contributors to increase in power losses. The comparison shows that the DDES turbulence model provides more accurate predictions of the hydraulic performance of stall conditions and visualizing flow field characteristics.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 3","pages":"1184-1204"},"PeriodicalIF":3.5,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first strategy is based on designing the blade through the selection of the beam material. Aluminium and aluminium foam with different porosity levels are considered for the beam material. The moduli of elasticity of the foams were calculated using the Mori-Tanaka approach and ranged from 70 GPa for solid aluminium to 23.3 GPa for foams with 50% porosity. Then, using these results, the finite element simulations under various loading conditions are performed. It is observed that increasing the foam porosity from 0% to 50% results in a 50% reduction in beam weight, with only a 35% decrease in the specific stiffness. The second strategy involves a topology optimisation of the internal beam to determine the most structurally efficient geometry for the blade through finite element analyses. Aluminium is considered the beam material for topology optimisation studies. The topology optimisation leads to a 53% reduction in the beam mass compared to the initial design, while maintaining performance metrics within acceptable limits. The mechanical behaviour of blades designed with these two strategies is investigated in eight different positions during a complete revolution in steady-state. The results are compared to each other, as well as a blade with a balsa beam as a benchmark.

All the member countries predominantly rely upon imported fossil fuels for power generation. In line with the vision of SAARC, this research explores the potential of renewable energy and provides a quantitative cross-border electricity trade assessment and its social-economical-technical (SET) impact on the SAARC region. The research presented in this article signifies the need for cross-border electricity trade to fulfill the ever-increasing demand-supply gap in the region by providing a rudimentary framework. This approach has the viable potential for alleviating the substandard quality of life in the region. The paper highlights near-border cities of SAARC countries that can potentially perform cross-border electricity trade in the SAARC region. In the first phase, near-border cities of the SAARC countries are highlighted.

Due to their low current magnitude, conventional protective equipment, such as overcurrent relays, cannot detect these faults. Alternatively, the waveform and variation range of current in HIFs are similar to other phenomena, such as linear and nonlinear load changes and capacitor banks. This paper employs a support vector machine (SVM) classification algorithm that demonstrates reliable accuracy and discrete wavelet transform (DWT) in HIF detection. First, the data set containing measured current signals of HIFs is collected to implement this approach. Then, DWT decomposes it to extract the features of each sample in the data set. The extracted features from this part are used as input to the SVM classification algorithm. The proposed idea is initially implemented on the IEEE 34-bus distribution test network. The proposed method achieves high capability and accuracy in detecting high-impedance faults. The proposed method is also applied to a real power distribution network in Markazi Province of Iran, yielding satisfactory results. EMTP-RV simulation software is used to simulate and evaluate the proposed method for power network modeling. Moreover, MATLAB software is used for feature extraction, and Python programming language in Google Colab and Spyder environment is applied to implement the SVM algorithm.

Active power filters are often used to mitigate harmonics; however, these solutions are complex due to the use of control techniques like the synchronous reference frame and can introduce additional harmonic currents during compensation within electrical systems. This study investigates the effects of different nonlinear loads on the power quality of solar microgrids and explores the reduction of harmonics from VFDs through the application of passive harmonic filters (PHFs). The objective was achieved by measuring harmonics generated by nonlinear loads and simulating a modeled VFD circuit using MATLAB/Simulink R2021b software, considering the demand side. Analysis of current harmonics measurements at the point of common coupling revealed that the total harmonic current distortion (THCD) for UPS, VFDs, and rectifiers was 20.64%, 42.82%, and 22.59%, respectively, while the total harmonic voltage distortion (THVD) for UPS, VFDs, and rectifiers was 27.83%, 31.55%, and 29.16%, respectively. Moreover, the total losses caused by harmonic distortion from these nonlinear loads is 860 Watts. Among these loads, VFDs were the dominant source of harmonics. Therefore, the application of passive harmonic filters (PHFs) was proposed to minimize harmonics in solar microgrids, adhering to the standards set by the Institution of Electrical and Electronics Engineers (IEEE) and the International Electro-Technical Commission (IEC).

In this study, the rate of cavity growth and the crack propagation mechanism in brittle coal samples under high thermal conditions are investigated using a two-dimensional particle flow code (PFC2D). Coal samples with different cleats' orientation under thermal environments are numerically simulated. The numerical modeling results show that the induced thermal stress is one-third of the coal sample failure stress. This is due to the increase in particles' volume, the change in normal force between the particles' bonds, and the changes in thermal and mechanical parameters resulting from the applied source temperature, which breaks the bond around the particle. The effects of heat and heterogeneity on the strength of coal samples are also studied under different temperatures ranging from 50°C to 900°C. The results showed that the presence of high-strength coal seams reduces the formation and propagation of heat-induced cracks, consequently reducing the cavity growth rate. The soft coal sample has more plasticity, and the cavity growth rate in the soft coal is more than that of the hard coal. The elasticity modulus and uniaxial compressive strength decrease with the increase of the source temperature and the sample begins to deform in a plastic mode.
