The assessment of indoor environments in rural houses across three regions in Shaanxi Province reveals that the existing heating systems are inadequate to meet the thermal requirements of residents. A comprehensive examination was conducted on the climate and available resources within six selected cities in rural Shaanxi. Economic evaluations were performed using the levelized cost of heat (LCoH) method to compare suitable heating schemes for these cities. The results demonstrate that considering both price and reserves of natural gas and biomass, the biomass boiler (BB) and gas boiler (GB) heating system are preferred. In four cities located in central and southern Shaanxi, BB offers the most economical solution with a minimum LCoH at 0.0963 CNY/kWh. GB proves to be more cost-effective in two cities in northern Shaanxi. Additionally, it is recommended to consider implementing a solar-air source heat pump composite heating system (S-ASHP). The suggested solar fraction ranges from 9% −14% in central and southern Shaanxi, while reaching 27% in Yulin. These findings effectively inform decision-making regarding the selection of clean heating modes based on economic considerations in rural areas.</div></div>","PeriodicalId":8201,"journal":{"name":"Applied Thermal Engineering","volume":"274 ","pages":"Article 126719"},"PeriodicalIF":6.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924399","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}

In this paper, simultaneous visual and thermal experiments are conducted on flat-plate pulsating heat pipes with a hydraulic diameter of 0.691 mm. The nitrogen pulsating heat pipes of 5-turn, 10-turn and 20-turn are measured at inclination angles from 0° to 90°. With the filling ratios of 40 %–54 %, the gravity dependence of the operation is investigated using coupled analysis of heat transfer and two-phase flow. Small gravity component along the channel restricts the liquid reflux and deteriorates the heat transfer, and the thermal conductivity can decrease below 0.3 times. High turn numbers improve the heat transfer and reduce the gravitational influence, with the highest thermal conductivity of 3674 W/(m·K) achieved for 20-turn vertically. Since nitrogen has small saturated pressure gradients, only the 20-turn operates horizontally. The operational mechanism is analyzed considering the interfacial characteristics. The two-phase flow instability is thermally driven and generates local pressure unbalance. The evaporation momentum force originates from the rapid expansion in the confined channels, which drives the pulsation. Moreover, the failure at high heat loads and large filling ratios is caused by the suppression of flow instability. It is discussed considering the flow stiffness of a two-phase flow system, which depends on the compressibility of the bubbles.</div></div>","PeriodicalId":8201,"journal":{"name":"Applied Thermal Engineering","volume":"274 ","pages":"Article 126712"},"PeriodicalIF":6.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941770","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 thermal separation performance of vortex tube is based on its geometrical configuration. It has already been observed in the previous literature of CDVT that the performance of vortex tube can be improved up to 56% by replacing the straight tube geometry with convergent-divergent type tube and the working gas of air with helium. However, no investigation has been done previously for other working gases in CDVT. Therefore, exploring the influence of other working gases on the thermal separation performance of CDVT is also very important. In order to extend the previous work and comprehend the impact of various gas properties on the flow phenomena and thermal separation performance of Convergent-Divergent vortex tubes (CDVT), this paper presents an extensive 3D CFD study using six working gases: helium, neon, argon, nitrogen, carbon dioxide, and air. This CFD study is conducted for a broad range of cold mass fractions. CFD simulation is done for the thermal separation analysis and the investigation of variation in fluid flow six different working gases in CDVT. Simulation is done in ANSYS Fluent with 3D geometry of fluid domain considering the structured hexahedral mesh and standard κ–ε turbulence model. While the nature of the flow is found unaltered for various gases, it is found that the values of velocity and temperature distributions inside CDVT vary for different gases because of the variations in the molecular weights and specific heat ratios of the gases. While heating and cooling capacities are greater for larger values of specific heat and higher temperature separations, both hot and cold temperature separations found to increase with increasing specific heat ratios.

The system employs direct thermal energy storage via PCM and indirect cooling through LCPs within a module comprising twelve cylindrical LIBs of the 18,650 type. Numerical simulations are conducted to investigate the cooling performance under a 3C discharge rate, examining the effects of LCPs quantity (1–4), BTMS shape, inlet velocity (0.05–0.2 m/s), and reciprocating cycle period (140-560 s).

The hybrid system exhibits superior performance in both low-temperature warm-up and high-temperature thermal regulation operations.

Conjugate heat transfer (CHT) analysis is conducted to study the flow characteristics, cooling performance, and temperature uniformity. The results depict that the structure with effusion holes located at the valley exhibits the best comprehensive cooling performance under all operating conditions.

This study investigates the energy consumption and emissions of a PHEV using a chassis dynamometer in a laboratory environment. We conducted experiments and analyses on energy flow, energy consumption, CO₂ emissions, and gaseous pollutant emissions from automobiles. Our findings indicate that during PHEV operation, the battery voltage ranges from 320 to 370 V, while the current fluctuates between −200 and 200 A, with voltage and current trends exhibiting opposite behaviors. The energy consumption of the vehicle when powered by electricity is significantly lower than that when driven by the internal combustion engine. Specifically, energy consumption in charge-sustaining (CS) mode, which involves the combined operation of the battery and engine, is more than twice that in charge-depleting (CD) mode, where only the battery is utilized. However, the CS mode demonstrates a greater potential for energy recovery compared to the CD mode, particularly when operating at an initial state-of-charge (SOC) of 23.3 %, where the power supplied exceeds the consumed power by approximately 19.37 %.

This facile approach enables precise tuning of surface roughness parameters, including peak-to-valley height, interfacial area ratio, surface slope, and arithmetic mean height, by controlling etching time.

The estimation of the phase change properties is performed through thermodynamic paths that connect two points along the liquid–solid saturation curve. The analysis leads to some conceptual differences between the latent heat estimated by other authors and the latent heat obtained in this work. Additionally, the elastic properties of core–shell systems are coupled to the proposed equations at saturation. A set of general equations for the volumetric and gravimetric energy densities in compressible media, is introduced. The proposed equations for energy densities incorporate the isothermal compressibility of liquid and solid phases. The equations introduced, provide a more realistic estimation of energy storage capacity in confined systems than previous models, where the compressibility is not considered. Consequently, it is possible to introduce a high compressible limit, which is shown to represent an ideal behavior, where materials have a maximum energy storage capacity. Thermal performance of confined PCMs can be improved by assessing the energy storage capacity of materials with finite compressibility in comparison with their corresponding high compressible limit. The energy storage efficiency of a particular core–shell configuration, is defined as the ratio between the energy density and its high compressible limit. The key thermodynamic and elastic parameters that contribute to the behavior of several core–shell combinations in relation to their proximity to the high compressible limit, are identified. Several configurations of different high temperature salts and shell materials, are analyzed through a balance between energy storage efficiency and crude energy density values. Experimental results from other authors in copper-alumina systems with a sacrificial layer, are used to validate the results of this work.
