A series of explosion welding experiments were performed using copper plates (in air, helium, and argon) and titanium plates (in air and argon) with lengths of 0.6 and 1 m, respectively. Low-inertia planar copper–constantan thermocouple sensors were placed in the gap to record the time-dependent temperature changes at the \"hot\" sensor junctions. Based on the obtained temperature curves, the numerical solution of the inverse problem of thermal conductivity was applied to reconstruct the heat fluxes from the SCG acting on the plate surfaces during the entire exposure period. Targets placed in the gap between the plates allowed for the investigation of cumulative processes during oblique plate collisions, as well as the analysis of metal particle distribution formed by the dispersed cumulative jet along the gap length. It was determined that the size of the SCG region and the distribution of heat flux power along its length were influenced by the density of both the gas and the dispersed metal particles, as well as the particle concentration along the length of the SCG. During the explosion welding of copper plates in helium and air, the particles are evenly distributed along the gap, with heat fluxes of 0.3 and 0.4 GW/m², respectively. However, when the medium is replaced with argon, the denser medium causes deceleration, leading to a redistribution of copper particles along the SCG region. These particles concentrate near the point of impact, resulting in a peak heat flux of approximately 1.8 GW/m². In the rest of the SCG, the heat flux remains at 0.2 GW/m². In this case, the shock wave front velocity in air, helium, and argon is the same, equal to 1.3 times the collision velocity (<em>V_c</em>). When welding titanium plates, the braking effect of the light, dispersed titanium particles, and their accumulation in the impact area are noticeable in the air and reach their maximum in argon. This leads to an increase in peak heat flux values to 1.0 and 3.6 GW/m², respectively. The average heat flux in the rest of the SCG is 0.3 GW/m² for both air and argon. Additionally, when switching from air to argon, the shock wave front velocity decreases from 1.3 to 1.1 times the <em>V_c</em>. The SCG heat exchange process with the surface of the plates was analyzed using numerical modeling, providing the temperature values of the surface layers before impact. The results show that when welding copper in air, helium, and argon environments, the surface temperature reaches 50–180 °C. In contrast, when welding titanium in an argon environment, the surface temperature can reach the melting point of titanium.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"244 ","pages":"Article 126920"},"PeriodicalIF":5.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576740","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}

Each stage is clearly defined, and its heat transfer characteristics are analyzed. The Thermal Establishment Stage, influenced by the entrance effect, exhibits superior heat transfer performance. In horizontal tubes, buoyancy-induced thermal stratification and secondary flow significantly extend the range of the entrance effect and intensify its impact.

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.

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.

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.

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/cm². 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.
