Extreme weather conditions generate intricate flow fields that not only affect the characteristics of flames but also substantially amplify the risk of jet fires spreading to neighboring equipment. In this work, a set of propane fire experiments was meticulously designed with nozzle wall spacing of 0.03 m, 0.20 m, 0.35 m, and ∞; the coupling effects of cross-wind velocity (0.00–3.12 m/s) and nozzle angle (0–120°) on the flame were also considered. The results show that the presence of sidewalls leads to oscillating tilted jet flames and a reduced wind velocity at the blow-out limit. For horizontal and downward-sloping jet fires, the sidewalls lead to an increase in flame vertical height. In addition, the sidewalls could reduce the flame pulsation frequency. A dimensionless model was developed to predict the vertical height of the jet flame under the influence of the cross-wind coupled with the sidewalls.

This paper innovatively proposes a pump-driven two-phase cooling system oriented toward chip-level thermal control and conducts in-depth experimental research on the influence of dynamic thermal loads on the thermal response characteristics of the cooling system. The experimental results indicate that the cooling system can swiftly achieve a stable transition within 4–5 s during load fluctuations. The study reveals that the heat conduction within the chip and the thermal conduction of the TIM account for 71.6 % of the chip's heat transfer thermal resistance. Under extreme test conditions, the maximum temperature difference between chip cores can reach 16 °C. In addition, by increasing the operating temperature of the cooling system, the heat transfer temperature difference of the cooling system can be reduced. The experiments also find that starting and operating the system by loading servers one by one from the bottom of the cabinet upwards is the recommended approach for this system. The safe operating range of the system is determined to be when the outlet quality is below 0.77. Within this range, the cooling system can stably support the start-stop operations of servers as well as dynamic load switching, thereby ensuring the efficient and stable operation of the data center.</div></div>","PeriodicalId":341,"journal":{"name":"International Journal of Thermal Sciences","volume":"217 ","pages":"Article 110070"},"PeriodicalIF":4.9,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321838","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}

Conduction primarily contributes to heat transfer, while convection is the main driver of mass transfer. However, conventional drying systems are heavily dependent on steam, usually powered by fossil fuels, and are often energy-inefficient with high levels of waste. Additionally, these surface-driven processes result in a lower percentage of energy absorption compared to the energy supplied, leading to significant energy losses. To improve this long-standing process, an experimental system was developed to investigate a process intensification approach involving the integration of Radio Frequency (RF) heating, a volumetric electromagnetic technology, alongside traditional conduction and convection drying methods. This study also emphasizes the use of sensors to continuously monitor key parameters such as moisture content, supply system temperatures, sample temperatures, air flows, and drying rates in real-time. The effect of RF as an auxiliary energy source in localized environments at varying moisture levels was explored to optimize industrial drying systems, quantify potential improvements, and provide insights for future studies. Experimental results from trials combining RF with convection and with the base case alternating conduction-convection drying processes are presented. It is shown that RF is a viable process intensification approach for paper drying improving the drying rate and energy intensity at higher moisture contents. These findings offer valuable insights for process intensification and contribute to the process development, modeling, and simulation of advanced paper drying techniques.</div></div>","PeriodicalId":341,"journal":{"name":"International Journal of Thermal Sciences","volume":"217 ","pages":"Article 110069"},"PeriodicalIF":4.9,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312685","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}

Electroslag remelting (ESR) technology has demonstrated excellent performance in removing inclusions from electroslag ingots. Typically, four primary pathways exist to remove and capture inherited inclusions from the electrode in the ESR process. Current numerical simulation research typically focuses on modeling two or three of these pathways. This study, presents a highly accurate model that integrates the electromagnetic field with the flow field and heat transfer throughout the entire process of inclusion movement, removal and capture processes in ESR. To validate the model's accuracy, a 2 t industrial-scale ESR furnace was utilized to prepare hot work tool steel H13. The model's ability to predict the distribution of inherited inclusions from the electrode was confirmed by comparing the metal droplet size in the residual electrode and the distribution of inclusions in the electroslag ingot as measured in industrial production. The results reveal that the proportion of inclusions exuded from the liquid metal film decreased as the size of inclusions increased from 5 to 20 μm. The proportion of inclusions that escape from the droplets and float up from the metal pool exhibited a significant increase. Notably, the escape of inclusions from metal droplets accounts for a substantial proportion (exceeding ten percent), and this stage is a crucial factor that must be considered in industrial-scale models.</div></div>","PeriodicalId":341,"journal":{"name":"International Journal of Thermal Sciences","volume":"217 ","pages":"Article 110090"},"PeriodicalIF":4.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307000","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 found that under pyrolysis conditions, the flame temperature near the PMMA wall gradually increases during the initial stage, while in the later stages of combustion, the near-wall flame temperature begins to decrease. Meanwhile, changes in the burner configuration affect the pyrolysis process, leading to variations in the onset range of the temperature decrease near the wall at different heights. Additionally, changes in the aspect ratio and heat release rate influence flame characteristics, causing distinct impacts on heat transfer to the pyrolysis wall. Increasing the aspect ratio reduces the incident radiative heat flux received by the wall, altering the contribution of the highest temperature range to the mass loss rate. In contrast, increasing the heat release rate has a smaller effect on the heat flux distribution across the PMMA panel during the steady stage.
