    Evaluation of the Failure Impact of Jet Fire from Natural Gas Leakage on Parallel Pipelines

    Zezhi Wen1, Kai Zhang1, Shanlin Liang2, Liqiong Chen1,*, Zijian Xiong1

    Structural Durability & Health Monitoring, Vol.20, No.1, 2026, DOI:10.32604/sdhm.2025.066408 - 08 January 2026

    Abstract Maintaining the structural integrity of parallel natural gas pipelines during leakage-induced jet fires remains a critical engineering challenge. Existing methods often fail to account for the complex interactions among heat transfer, material behavior, and pipeline geometry, which can lead to overly simplified and potentially unsafe assessments. To address these limitations, this study develops a multiphysics approach that integrates small-orifice leakage theory with detailed thermo-fluid-structural simulations. The proposed framework contributes to a more accurate failure analysis through three main components: (1) coupled modeling that tracks transient heat flow and stress development as fire conditions evolve; (2)… More >

    Porosity-Impact Strength Relationship in Material Extrusion: Insights from MicroCT, and Computational Image Analysis

    Jia Yan Lim1,2, Siti Madiha Muhammad Amir3, Roslan Yahya3, Marta Peña Fernández2, Tze Chuen Yap1,*

    CMC-Computers, Materials & Continua, Vol.86, No.2, pp. 1-19, 2026, DOI:10.32604/cmc.2025.070707 - 09 December 2025

    Abstract Additive Manufacturing, also known as 3D printing, has transformed conventional manufacturing by building objects layer by layer, with material extrusion or fused deposition modeling standing out as particularly popular. However, due to its manufacturing process and thermal nature, internal voids and pores are formed within the thermoplastic materials being fabricated, potentially leading to a decrease in mechanical properties. This paper discussed the effect of printing parameters on the porosity and the mechanical properties of the 3D printed polylactic acid (PLA) through micro-computed tomography (microCT), computational image analysis, and Charpy impact testing. The results for both… More >

    Impact of Data Processing Techniques on AI Models for Attack-Based Imbalanced and Encrypted Traffic within IoT Environments

    Yeasul Kim1, Chaeeun Won1, Hwankuk Kim2,*

    CMC-Computers, Materials & Continua, Vol.86, No.1, pp. 1-28, 2026, DOI:10.32604/cmc.2025.069608 - 10 November 2025

    Abstract With the increasing emphasis on personal information protection, encryption through security protocols has emerged as a critical requirement in data transmission and reception processes. Nevertheless, IoT ecosystems comprise heterogeneous networks where outdated systems coexist with the latest devices, spanning a range of devices from non-encrypted ones to fully encrypted ones. Given the limited visibility into payloads in this context, this study investigates AI-based attack detection methods that leverage encrypted traffic metadata, eliminating the need for decryption and minimizing system performance degradation—especially in light of these heterogeneous devices. Using the UNSW-NB15 and CICIoT-2023 dataset, encrypted and… More >

    Structural Optimization of Nozzles for Gas-Liquid Two-Phase Jets

    Fengxia Shi1, Jian Zhao2,3,*, Xiaodong Dai1, Guoxin Zhang4, Yuan Lu4, Yuyan Shang1

    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.12, pp. 2963-2980, 2025, DOI:10.32604/fdmp.2025.073836 - 31 December 2025

    Abstract Gas–liquid two-phase jets exhibit markedly enhanced impact performance due to the violent collapse of entrained bubbles, which generates transient microjets and shock waves. The geometry of the nozzle is a decisive factor in controlling jet formation, flow modulation, and impact efficiency. In this work, the structural optimization of gas–liquid two-phase nozzles was investigated numerically using the Volume of Fluid (VOF). Simulation results show that the aero-shaped nozzle delivers a significantly stronger impact on the target surface than conventional geometries. Specifically, its impact pressure is 21% higher than that of a conical straight nozzle and 37%… More > Graphic Abstract

    The Impact of EU Immigration Law and Policy on Immigrants’ Subjective Well-Being

    Quan Cheng, Yun Lin, Hui Yu*

    International Journal of Mental Health Promotion, Vol.27, No.12, pp. 1961-1988, 2025, DOI:10.32604/ijmhp.2025.072232 - 31 December 2025

    Abstract Background: Against the backdrop of the complex interplay between global migration flows and the European Union’s governance system, immigrants’ subjective well-being (SWB) has become a crucial indicator for assessing both their social integration and the effectiveness of integration policies. However, few studies have systematically linked immigration law and policy to SWB through a structured framework of human needs. This study aims to assess how European Union (EU) immigration policies influence immigrants’ SWB by facilitating the fulfillment of hierarchical needs based on Maslow’s theory. Methods: Using data from the European Social Survey (ESS, 2010–2023), this study analyzed… More >

    Investigation of Droplet Impact on Hot Surfaces Based on Thermal Lattice Boltzmann Method

    Xiaoyan Zhuo1, Yukun Ji1, Yatao Ren1,*, Xuehui Wang2, Hong Qi1

    Frontiers in Heat and Mass Transfer, Vol.23, No.6, pp. 1701-1720, 2025, DOI:10.32604/fhmt.2025.074045 - 31 December 2025

    Abstract Flow and heat transfer characteristics during droplet impact on hot walls are pivotal for elucidating the mechanisms of spray cooling and exploring pathways for heat transfer enhancement. When the wall temperature exceeds the Leidenfrost point, a vapor film forms between the droplet and the wall, rendering the heat transfer process highly complex. Furthermore, for droplet impact on curved walls, the presence of curvature introduces additional factors that modify the spreading behavior of the droplet and necessitate in-depth analysis. Therefore, this work investigates the flow and heat transfer dynamics of droplet impact on hot planes and… More >

    The Failure Analysis of Carbon Fiber-Reinforced Epoxy Composites against Impact Loading with Numerical and Experimental Investigations

    Md Salah Uddin*

    Journal of Polymer Materials, Vol.42, No.4, pp. 1051-1073, 2025, DOI:10.32604/jpm.2025.070688 - 26 December 2025

    Abstract Carbon fiber-reinforced composites (CFRCs) have a wide range of applications in the aerospace, automotive, and energy sectors. A higher specific strength-to-weight ratio is desired in high-performance applications. The failure mechanism of CFRCs involves multiscale phenomena, such as failure that can occur at the matrix, fibers, interface, layers, lamina, and laminates. When an impactor hits the CFRCs, the design involves analyzing each of these stages to prevent failure and optimize the properties of CFRCs under various loading conditions. A numerical model was employed to predict the fracture toughness of CFRCs with varying weight fractions and orientations.… More >

    Yongwei Li1, Kaituo Jiao2,*, Dongxu Han3, Bo Yu2, Xiaoze Du1

    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.3, pp. 3453-3479, 2025, DOI:10.32604/cmes.2025.073239 - 23 December 2025

    Abstract The permeability contrast between the Hot Dry Rock (HDR) reservoir and the surrounding formations is a key factor governing fluid loss in Enhanced Geothermal Systems (EGS). This study thus aims to investigate its impact on system performance under varying operating conditions, and a three-dimensional thermo–hydro–mechanical (THM) coupled EGS model is developed based on the geological parameters of the GR1 well in the Qiabuqia region. The coupled processes of fluid flow, heat transfer, and geomechanics within the reservoir under varying reservoir–surrounding rock permeability contrasts, as well as the flow and heat exchange along the wellbores from… More >
