Heat exchangers, turbine blade cooling, electronic component cooling, cooling of combustion chambers, paper drying applications, textile industries, food industry, pharmaceuticals, glass and polymer tempering processing, and laser material processing are all examples of where impinging jets are employed. These applications leverage efficient HT capabilities of jet impingement to enhance performance and energy efficiency. By optimizing design and operation of impinging jets, industries can achieve significant improvements in temperature control and product quality. The influence of nozzle inclination and nozzle spacing distances on HT is discovered to have a significant impact. The goal of this study is to investigate convective HT behavior of turbulent jet impingement at various inclination degrees and nozzle-to-nozzle separation distances. This study can be used to cool electrical equipment as well as automotive parts. By adopting a precise inclination angle and a specified nozzle-to-nozzle spacing, rate of HT can be increased.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"151 6","pages":"4957 - 4972"},"PeriodicalIF":3.1,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147727607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when it is compounded with different polar phase change materials, the prepared phase change aggregates show significant differences in performance, and its mechanism of action has not yet been clarified, which needs to be studied in depth. In this paper, phase change aggregates were prepared by using ceramsite to adsorb polar phase change material PEG and nonpolar phase change material paraffin, respectively. The adsorption test revealed that the main driving force for the adsorption of PCMs by ceramsite under atmospheric pressure is capillary force, and the polarity of PCMs affects the adsorption capacity of ceramsite, but this effect can be neglected under negative pressure (− 1 MPa). DSC test showed that the effect of ceramsite on the phase change properties of PEG was more significant compared to paraffin, and the crystallization rate of PEG/ceramsite was only 86.32%. By weakening the hydrogen bonding between PEG and ceramsite, it was found that hydrogen bonding is the main reason for the large changes in the phase transition properties of PEG. On the one hand, hydrogen bonding provides nucleation sites for PEG to reduce the degree of supercooling, and on the other hand, hydrogen bonding restricts the normal crystallization of PEG molecules. After quantitatively analyzing the leakage process, it was found that the polarity relationship between ceramsite and PCMs determine the leakage rate by regulating the contact angle at the interface between the two. It was calculated that the critical pore size for leakage of PEG/ceramsite was greater than the vast majority of the pore size of ceramsite. The surface tension generated in the pore size of the ceramsite is sufficient to counteract the effect of PEG gravity, thereby ensuring the stability of the phase change aggregates in their definitive form.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"151 5","pages":"4449 - 4470"},"PeriodicalIF":3.1,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147808209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the number of modules shifts the ignition point axially leftward and extends the cook-off time. Across all conditions, the cook-off temperature range is 451–463 K.

The study introduces a solar-powered vapor compression refrigeration system using CO₂ as a low-GWP refrigerant integrated with a heat exchanger to enhance COP through analytical performance evaluation with and without superheating. The energy analysis and performance assessment of a milk-cooled chiller with a solar-powered refrigerant compressor are also the main topics of the study. Using CO₂, a novel refrigerant with low GWP (global warming potential) and ODP (ozone depletion potential), this study compares the performance of the vapor compression refrigeration cycle with and without superheating. Here, the new refrigerant has been discussed. Reducing the compressor’s labor or enhancing the refrigeration effect are two ways to raise the COP of the refrigeration system (VCRS). Reducing compressor effort and increasing refrigerating effect are necessary to improve the coefficient of performance. The typical vapor compression refrigeration (VCR) cycle, which is used in many refrigeration systems, has a low Coefficient of Performance (COP).

The main cooling paint approaches are categorized as reflective, radiative, and hybrid cooling paints. Reflective cooling paints like TiO₂- and BaSO₄-based cooling paints are effective in reducing operating temperatures and improving solar reflectance with possible efficiency retention of 2–3%. Radiative cooling paints are characterized by high solar reflectance and high infrared emittance to ensure cooling in the night and restricted thermal cycling with possible cooling of up to 7.2 °C to ensure improved longevity of PV devices. Hybrid cooling paints are designed to ensure effective cooling in the daytime and nighttime with improved cooling of up to 15.6 °C; some studies also reported possible relative efficiency improvements of 29.6%. Although these cooling paints have shown improved efficiencies and cooling effects, they are limited by factors such as photoaging by UV radiation, durability in the outdoors and soiling effects, scalability to real-world PV systems, and the complexity between emittance and cost-effectiveness.

The icing mechanism, influencing factors and influencing factors of SLD·(supercooled large droplet) impacting wing are systematically analyzed and numerically simulated. On this basis, the fluid–solid coupling heat transfer characteristics of the hot air anti-icing system are analyzed. It is revealed that the temperature field of the leading edge of the wing is nonuniformly distributed due to the increase in the bleed air temperature. The absorption temperature of the latent heat in the icing area is lower than that in the non-icing area, and the latter is fully heated to increase the temperature difference by 67%. The purpose is to provide reference for the development of efficient and reliable anti-icing system, which is of great significance for ensuring the safety of aviation flight.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"151 5","pages":"4471 - 4495"},"PeriodicalIF":3.1,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147808224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Granules were formed by using the synthesized PDP, dried lupin leaves, and calcium lignosulphonate as a binder, with up to 72.69% of granules in the commercial fraction (2–5 mm).

Thermal analysis (STA/DSC) confirmed granule stability up to 190 °C, indicating that the additives did not negatively affect thermal properties and that the granules are suitable for industrial drying and granulation conditions. SEM analysis showed irregular surface morphology and high moisture absorption, suggesting the need for protective coatings.
