In this work, the ultra-thin flexible polymer heat pipes (FPHPs) were fabricated using hydrophilic nylon mesh wicks (HNMWs), aluminum-plastic film casings, and composite support structures consisting of coarse nylon mesh and polyimide (PI) vapor channel. The HNMWs with outstanding hydrophilicity and capillary performance exhibit a low water contact angle of 15.9°, a high equilibrated wicking height of 81 mm, and a significantly high capillary coefficient of 9.36 mm/s<sup>0.5</sup>. The effects of working fluid filling ratio, mesh number of coarse nylon mesh, and thickness of PI vapor channel, on the heat transfer performance of FPHPs were investigated. Results demonstrate that the optimal filling ratio is 100 %, and that both the mesh number of coarse nylon mesh and thickness of PI vapor channel positively correlate with heat transfer performance of FPHPs. Additionally, the FPHPs achieve outstanding heat transfer performance, with a maximum heat transfer power of up to 11 W, a high equivalent thermal conductivity of up to 9737.58 W/(m·K), and a low thermal resistance of 0.15 K/W. The FPHPs display excellent flexibility with a low thermal resistance of 0.17 K/W, representing only a 13.3 % increase from the value without bending.

Furthermore, emissivity modulation is essential for improving the effectiveness of infrared camouflage, especially in complex environments. This study presents a tunable multiband-compatible laser camouflage system featuring a layered configuration consisting of ZnS/Ge/MgF<sub>2</sub>/Ge/IST/W. This structure shows excellent camouflage performance across various spectral bands, including visible light, near-infrared, mid-wave infrared (3–5 μm), and long-wave infrared (8–14 μm), as well as at laser detection wavelengths of 1.06 μm and 1.54 μm, both before and after the IST phase transition. The emissivity modulation of the non-atmospheric window (NAW) band is achieved by controlling the phase state of the phase-change material IST. In its crystalline state, the NAW band exhibits increased emissivity, which aids in heat dissipation and cooling when the target temperature exceeds the background temperature. Conversely, when the background temperature exceeds the target temperature, the structure shifts to an amorphous state, leading to reduced NAW emissivity that minimizes thermal loss. This adjustment allows the target temperature to align more closely with the environment, thereby enhancing camouflage effectiveness. Through thermal imaging simulations of the two phase-change states, this study clearly illustrates the camouflage capabilities of the structure over a range of temperatures, emphasizing its significant potential for adaptive multiband camouflage.

Bubble dynamics were systematically documented by high-speed imaging, while localized temperature measurements were utilized to construct pool boiling curves and heat transfer coefficient (HTC) profiles. Experimental results reveal that effective bubble nucleation sites on blister surfaces are concentrated at the bottom edges of blisters. Bubble dynamics in blister zones are governed by two mechanisms: curvature-induced surface tension amplification and buoyancy enhancement driven by edge-localized vapor nuclei. The protrusion geometry of blisters significantly disrupts vapor coverage, with blisters ≥ 2 mm in height exhibiting continuous vapor film disruption after the critical heat flux (CHF) is reached. Compared to conventional surface, blister surfaces exhibit 9.37–39.82 % CHF reduction. Furthermore, the heat transfer characteristics of blister surfaces are governed by the competition between geometry-enhanced thermal performance and thermal resistance-induced heat transfer deterioration: at low-to-medium heat fluxes, the HTC of blister surfaces generally exceeds that of conventional surface, whereas at high heat fluxes, the HTC of blister surfaces rapidly decreases and induces earlier CHF onset.

Especially for lean-burn nature gas engines, near-wall quenching results in a large amount of methane slip which leads to a unneglectable greenhouse effect. Research on flame quenching under ultra-lean combustion and at elevated pressures are lacking, which contributes to UHC prediction in lean-burn nature gas engines. In this study, quantitative measurements of the quenching distance for lean CH<sub>4</sub>/air laminar premixed flames were carried out at elevated pressures. Deep insight of near-wall quenching behaviors and flame propagation characteristics for laminar premixed CH<sub>4</sub>/air flames were proposed through simultaneous high-speed schlieren and CH* chemiluminescence micrography. Laminar flame thicknesses of different equivalence ratios were released to reveal the relation between the flame front structure and wall-quenching characteristics, and the effects of flame front structure on the near-wall quenching were evaluated. Normal thermal gradient of the boundary layer at the near-wall region was calculated through the measured heat flux by employing high-speed heat flux sensors. Furthermore, dimensionless parameters as Nusselt number (<em>Nu</em>) and Peclet number (<em>Pe</em>) were derived to clarify the relation between the wall heat transfer and near-wall flame quenching. The result shows that quenching distances decrease exponentially with larger equivalence ratios, while reaching a significantly large distance near the lean limit (<em>ϕ</em> = 0.5) in this study. Although thermal gradients increase rapidly with larger equivalence ratios, the higher reactivity resulting from larger equivalence ratios overweighs the thermal gradient effect, leading to smaller quenching distances. The quenching distance is inversely proportional to the initial ambient pressure at the range of 0.5∼3 MPa in this study. The wall thermal gradient, however, enhances with the increase of the initial ambient pressure. Due to the dimensionless analysis, the wall heat transfer shows a strong effect on the near-wall flame quenching significantly under elevated pressures and lean combustion conditions.</div></div>","PeriodicalId":8201,"journal":{"name":"Applied Thermal Engineering","volume":"274 ","pages":"Article 126708"},"PeriodicalIF":6.1,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912564","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}
