However, conventional circular impinging jets (CIJs) typically produce non-uniform heat transfer distributions, with high Nusselt numbers (<i>Nu</i>) at the stagnation point that rapidly decline in the wall-jet region, causing thermal stresses. This review critically analyzes the flow field and heat transfer performance of jet impingement from special-shaped holes, including swirling (threaded and twisted-tape), converging/diverging, lobed, chevron, cross-shaped, and racetrack nozzles. It synthesizes experimental and numerical studies examining the effects of nozzle geometry on jet structure, vortex dynamics, entrainment, turbulence generation, and local/average <i>Nu</i> distributions. Swirling impinging jets (SIJs) introduce tangential velocity through helical inserts or twisted tapes, generating additional streamwise and azimuthal vortices. These enhance radial momentum redistribution and significantly improve thermal uniformity. Non-circular orifices (lobed, chevron, and cross-shaped) promote stronger entrainment and axis-switching, yielding Nu enhancements of 25%–110% relative to circular jets, especially at low <i>H</i>/<i>D</i> ratios. The integration of nanofluids (Al<sub>2</sub>O<sub>3</sub>, CuO, TiO<sub>2</sub>, and hybrids) with both CIJs and SIJs is also examined. Nanofluids further augment heat transfer (typically 20%–75%) via increased thermal conductivity and microconvection, although they increase viscosity and pressure drop (Δ<i>p</i>). Key parameters, including Reynolds number (<i>Re</i>), <i>H</i>/<i>D</i>, swirl number, and nanoparticle concentration, are systematically evaluated using compiled data and correlations. The review concludes that special-shaped holes shift cooling from localized high-heat-transfer zones toward more uniform temperature distributions, making them suitable for gas turbine blades and electronics. Critical gaps remain in combined SIJ-nanofluid systems on non-planar surfaces and long-term nanofluid stability under high-shear conditions.</p>","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":"8 9","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.71047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite rapid progress, existing studies remain largely application-oriented, while the fundamental relationships among interface construction, hybrid architecture, stability, and functional performance are often examined independently. This review provides a critical and design-oriented perspective on BPQD hybrid systems with particular emphasis on interfacial engineering. Major interface-construction strategies, including van der Waals assembly, surface functionalization, covalent coupling, and in situ growth, are comparatively analyzed in terms of their structural features, advantages, and limitations. The interplay among component selection, dimensional architecture, interface configuration, and stability is further discussed to establish a unified framework for rational hybrid design. Representative advances in alkali-ion storage, electrocatalytic water splitting, nitrogen reduction, and photocatalytic hydrogen production are evaluated from the viewpoint of interfacial functionality. Finally, emerging directions involving stability-by-design concepts, scalable manufacturing, data-driven materials discovery, and integrated energy systems are highlighted.

This study proposes a novel real-time compositing framework based on a latent space diffusion model to efficiently integrate foreground and background elements while preserving structural consistency across frames. The pipeline employs a Matting Objective Decomposition Network (MODNet) to extract the foreground and corresponding alpha matte, followed by latent space encoding and diffusion-based compositing using conditional reverse denoising. To enhance temporal coherence, a temporal attention mechanism is incorporated to ensure frame-to-frame consistency. Additionally, a Deep Image Harmonization Network (DIHNet) is applied to align illumination and color between composited elements, improving perceptual realism. The proposed method is evaluated on Human-Centric Video Matting and HYouTube datasets under diverse lighting and motion conditions. Experimental results demonstrate superior performance, achieving a Peak Signal-to-Noise Ratio (PSNR) of 41.2 dB, Structural Similarity Index Measure (SSIM) of 0.958, Learned Perceptual Image Patch Similarity (LPIPS) of 0.067, and Fréchet Inception Distance (FID) of 13.1.
