This study develops a physics-informed thermo-magnetic model for an aqueous multi-walled carbon nanotube/poly(vinyl alcohol) coating applied to a continuously stretching cylindrical fiber. The coating medium is represented using a Jeffrey viscoelastic model and incorporates transverse magnetic forcing, cylindrical curvature, Cattaneo–Christov thermal relaxation, Brownian diffusion, and thermophoresis. Experimentally informed properties for a 14 wt% poly(vinyl alcohol) solution containing 0.25 wt% multi-walled carbon nanotubes are employed. The reduced boundary-value problem is solved numerically and verified against published stretching-cylinder benchmarks, with deviations below 0.12%. A coupled first-order physics-informed neural network, supplemented by sparse numerical state anchors, is subsequently trained across five nondimensional design parameters and assessed using 50 unseen parameter combinations. The maximum relative errors are 1.32% for reduced coating drag and 1.20% for reduced heat transfer, with coefficients of determination exceeding 0.998. Global variance analysis attributes approximately 65.2% and 34.8% of drag variability to magnetic interaction and curvature, respectively, whereas Brownian transport accounts for approximately 99.8% of heat-transfer variability. Evaluation of 262,701 candidate designs shows that the nondominated drag–heat-transfer region occurs at the lower Brownian-motion bound, after which the remaining trade-off is governed primarily by magnetic interaction and curvature. The principal advance is an integrated route from verified transport modeling to physics-informed parametric prediction, sensitivity interpretation, and multi-objective screening for continuous smart-fiber coating.</div></div>","PeriodicalId":332,"journal":{"name":"International Communications in Heat and Mass Transfer","volume":"180 ","pages":"Article 112936"},"PeriodicalIF":6.2,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149347066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coupled effects of micropillar geometry and wettability distribution on condensate transport remain unclear. Condensation on triangular, quadrangular, and hexagonal micropillar arrays is numerically investigated under hydrophilic, superhydrophobic, and hybrid wettability conditions. The results show that hydrophilic surfaces promote rapid condensate accumulation but suffer from flooding-induced thermal resistance, whereas superhydrophobic surfaces facilitate droplet coalescence and jumping but limit early-stage liquid formation. For hybrid wettability surfaces, where hydrophilic pillar tops are combined with a superhydrophobic substrate, a wettability gradient driven vertical migration mechanism transports condensate toward the pillar tops, suppresses flooding, and sustains suspended droplet growth. Among these configurations, the triangular hybrid micropillar array exhibits the best performance, achieving the highest peak heat flux of 1283 kW/m<sup>2</sup> and the highest liquid volume growth rate under the present subcooling condition. Compared with the corresponding superhydrophobic surfaces, hybrid wettability enhances the peak heat flux by 25.6%–41.7%.

To investigate the influence of bore coatings on the interior-ballistic dynamic response of a gun barrel, a three-dimensional coating–barrel–projectile coupled finite element model was established for a 12.7 mm-caliber barrel. Using a Cr-coated barrel as the baseline, the evolution of temperature and stress under different loading conditions and the local stress characteristics were analyzed, and the peak temperatures and peak stresses at a representative section were compared for different coating materials and thicknesses. The results show that the thermo-mechanical stress response gradually shifts from bore-pressure dominance in the early stage to thermal-load dominance in the later stage, while a pronounced projectile engraving-contact effect occurs in the forcing-cone region. The temperature and stress fields exhibit clear three-dimensional non-uniformity, and the land corner is prone to local temperature and stress concentrations. Coating material and thickness significantly affect the thermal and stress responses of the barrel. At the center of the land top, Cr exhibits the lowest peak temperature among the investigated coating materials, ranging from 766 to 822 K. When the coating thickness increases from 50 to 150 μm, the peak temperature and peak thermal stress at the corresponding substrate-side interface beneath the center of the land top decrease by 20.6%–45.2% and 5.6%–89.7%, respectively, for all coating materials. These findings can provide a reference for gun-bore protective design and the improvement of barrel service performance.</div></div>","PeriodicalId":332,"journal":{"name":"International Communications in Heat and Mass Transfer","volume":"180 ","pages":"Article 112907"},"PeriodicalIF":6.2,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149347070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
