However, current designs depend heavily on optimization algorithms that require extensive calculations. Therefore, achieving the rapid design of target-oriented spectral emitters remains a fundamental challenge. A comprehensive investigation into the mechanisms of microscale radiation regulation ensures the rapid design of spectral emitters. Among these mechanisms, magetic polaritons (MPs) have become a significant resonance mode in the field of micro nano scale thermal radiation due to its Perfect absorption. Equivalent inductor-capacitor circuit (LC) model is an important theoretical model for calculating the resonance frequency of MP, but it requires a constant for fitting, which seriously restricts the Fast design of micro-nano emitters. In this paper, transmission line (TL) theory is proposed to directly determine the frequency of MP excitation for grating and slit arrays without fitting. Numerical simulation results indicate that the MP excitation frequency calculated by TL theory are accurate. Moreover, TL model directly gives the fitting constants in the LC model. Compared with previous studies, TL theory has achieved the calculation of the excitation frequency of MP without fitting. Finally, as a practical application, TL model is employed to illustrate the Fast design of heat emitter. Our research seeks to facilitate the expedited design of target-oriented spectral emitters and to advance the application of LC model and TL model in spectral emitters.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"244 ","pages":"Article 126904"},"PeriodicalIF":5.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592359","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}

By analyzing the radial distribution function, radius of gyration, mean squared displacement, diffusion coefficient, and the binding energies between cellulose, hemicellulose, lignin, and SA, the study reveals the different roles each component plays in the adsorption of SA and elucidates the key mechanisms underlying the differences in the loading capacity of lignocellulosic biomass in composite PCMs. The results show that cellulose plays a critical role in the loading of SA, with a binding energy of -230.7 J/mol, significantly higher than that of hemicellulose and lignin. In addition, hemicellulose exhibits outstanding performance in enhancing the thermal conductivity of composite PCMs. Specifically, the thermal conductivity of the SA/hemicellulose system is 0.28 W/(m·K), which is 22 % higher than that of the SA/cellulose system and 47 % higher than that of the SA/lignin system.

The experimental study of rocket plume employs typically small-scale models. It is of great importance to establish the similarity relationships between the results of different scale models, as this is a crucial step in applying these findings to thermal analysis of actual rocket engines. This study compares the flow field characteristics and infrared radiation features of the rocket engine exhaust plume with and without afterburning effect based on non-aluminized HTPB propellant under a series of engine scale ratios ranging from 0.1 to 10. The exhaust plume uses reactive flows. When the incoming condition is air, the exhaust plume exhibits the afterburning effect, while there is no afterburning effect when the incoming condition is pure nitrogen. The exhaust plume flow field is obtained through computational fluid dynamics (CFD), and the radiation signal is calculated by solving the radiation transport equation using the line of sight (LOS) method. The simulation results indicate that the flow field parameter distribution and infrared image shapes of the exhaust plumes from rocket engines of different scales are similar; Compared to the non-afterburning exhaust plume, the radiance peak of exhaust plume with the afterburning reaction is increased by 4.62 % to 10.21 %. The gain in infrared radiation intensity caused by the afterburning effect increases with increasing scale in the 2.7–3.0 μm and 3.3–4.0 μm bands. In the 4.2–4.5 μm of waveband, the gain stabilizes as the scale increases. The relationship between the engine scale and radiation intensity is exponential, with the exponent being influenced by both the waveband and the nozzle pressure ratio (NPR). The exponent value falls within the range of 1.5 to 3.4. The results of this study contribute to the understanding of rocket motor exhaust plume flow and radiation characteristics, which can aid in their engineering assessment.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"244 ","pages":"Article 126895"},"PeriodicalIF":5.0,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576845","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 study also examines the dynamic response of the PEMEC stack to varying operating conditions, emphasizing the need for temperature control strategies to manage thermal gradients and prevent local hot spots.

Specifically, we extend the so-called constrained-LES (CLES) of wall-bounded turbulence to the scalar turbulence. CLES was first developed by Chen et al. (2012) to successfully resolve the mismatch problem of mean velocity profiles in detached-eddy simulations. Following the same methodology, here the scalar field is solved by using LES over the whole domain. A Reynolds averaged Navier–Stokes (RANS)-type of turbulent scalar flux is imposed onto the subgrid stress only within an inner layer adjacent to the wall boundary. Specifically, we utilize an eddy diffusivity model for the RANS turbulent scalar flux. With this constrain, the mean scalar profile of the inner layer can be accurately obtained while the small-scale structures in scalar field are still retained. The method is validated by the comparison with DNS of channel turbulence with passive scalar, and the results suggest that the current method can successfully resolve the log-layer mismatch in mean scalar profiles. The method can accurately generate the mean scalar profile, scalar fluctuation profile, turbulence scalar flux, and global Nusselt number for a wide range of Reynolds and Prandtl numbers in channel turbulence.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"244 ","pages":"Article 126892"},"PeriodicalIF":5.0,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576848","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}

This paper proposed a leaf vein manifold microchannel heat sink. The thermal-hydraulic performance and flow distribution characteristics of symmetric and asymmetric arrangements are comparatively analyzed by VOF transient flow boiling simulations. In comparison to straight microchannels, the leaf vein microchannels exhibited an increase in the wetted area and a reduction in the skewness of the flow distribution by 18%. These improvements contributed to a 4K cooler heated surface at 100 W/cm<sup>2</sup>. In addition, the asymmetric leaf vein microchannels reduced the thermal resistance by 5% in comparison to the symmetric structure, while the pressure drop remained unaltered. The enhancement of the asymmetric leaf vein structure on the thermal-hydraulic performance was found to be consistent across different heat fluxes and inlet velocities. Furthermore, it was observed that doubling the inlet flow rate resulted in a 29.7% reduction in thermal resistance of the heat sink, accompanied by a 130.6% increase in pressure drop. It is therefore recommended that a lower flow rate be employed to minimize the pumping power.
