This review explores the classification, properties, and integration of PCMs into solar technologies, including solar thermal collectors, photovoltaic (PV) systems, and concentrated solar power (CSP) systems. PCMs store and release thermal energy via phase transitions, with key thermophysical properties—such as high latent heat of fusion, thermal conductivity, and phase stability—being vital for improving energy storage and system performance. PCMs are classified into organic, inorganic, and eutectic types, each with distinct advantages and limitations. Organic PCMs (e.g., paraffins) are chemically stable and non-corrosive but have low thermal conductivity. Inorganic PCMs (e.g., salt hydrates) offer higher conductivity and storage capacity but face challenges like phase segregation and corrosion. Eutectic PCMs combine organic and inorganic elements, offering tunable melting points and enhanced thermal properties. The review highlights novel integration methods—encapsulation, impregnation, and nanoparticle incorporation—to improve PCM performance. Economic considerations, including cost-effective materials and sustainable manufacturing, are discussed. Emerging developments, such as composite PCMs and nanomaterials, are identified as key areas for future research, underscoring PCMs' role in advancing solar energy storage and supporting a sustainable energy future.</div></div>","PeriodicalId":332,"journal":{"name":"International Communications in Heat and Mass Transfer","volume":"165 ","pages":"Article 109094"},"PeriodicalIF":6.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106887","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 study investigates the flow features generated by applying passive flow control techniques, such as surface roughness, fins and riblets, where a favourable breakdown of the Reynolds analogy is required. Flow features can favourably break the Reynolds analogy if they produce greater turbulent or dispersive heat flux than the corresponding momentum flux. Currently, no reports indicate that homogeneous surface roughness can favourably break down the Reynolds analogy. This is primarily due to the dominance of pressure drag over viscous drag on rough surfaces. In contrast to rough surfaces, longitudinal riblets do not cause pressure drag and can result in a favourable breakdown of the Reynolds analogy for certain geometries. As we will discuss, the combination of the strong spanwise aligned Kelvin-Helmholtz (KH) rollers and weak streamwise aligned secondary flows is a promising approach for achieving a favourable breakdown of the Reynolds analogy in drag increasing riblets. However, more studies are needed to characterise KH rollers to generate KH rollers with desirable parameters. On the other hand, whether drag-reducing riblets can also achieve enhanced heat transfer remains unclear, as contradicting results have been reported.</div></div>","PeriodicalId":332,"journal":{"name":"International Communications in Heat and Mass Transfer","volume":"165 ","pages":"Article 108959"},"PeriodicalIF":6.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106884","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 is due to an increase in the energy consumption and the leakage currents as a result of the miniaturization which requires taking care of the thermal behavior to make sure that the device is working in the threshold temperature regime. The current work deals with a two-dimensional framework, incorporating the non-locality in space, for more accurate investigation of the micro/nanoscale heat transport using the lower computational cost phenomenological macroscopical Dual Phase Lag (DPL) method. The non-dimensional non-locality parameter <span><math><mi>γ</mi></math></span>, which indicates the strength of the nonlocality, is embedded through the modified DPL model named as non-local DPL (NDPL). In the present manuscript the two-dimensional silicon transistor, has been investigated. It is obtained that the <span><math><mi>γ</mi></math></span> parameter in <span><math><mi>x</mi></math></span> and <span><math><mi>y</mi></math></span> direction has the same value and like its behavior at one-dimension, is linearly dependent on the Knudsen number, Kn, being 1.5 for <span><math><mrow><mi>K</mi><mi>n</mi><mo>=</mo><mn>10</mn></mrow></math></span> and 0.015 for <span><math><mrow><mi>K</mi><mi>n</mi><mo>=</mo><mn>0</mn><mo>.</mo><mn>1</mn></mrow></math></span>. Also, the phase lagging ratio, B, is found to be unique value of 0.08 for all specified times and Knudsen numbers. It should be mentioned that although the effect of non-locality is more pronounced for smaller systems with higher Knudsen numbers in which the non-Fourier behavior is more evident, but contemplating the non-locality parameter in systems with lower Knudsen number, makes the results more precise. When the size of the layer in <span><math><mi>x</mi></math></span>-dimension, is two times the <span><math><mi>y</mi></math></span>-dimension, it is found that the temperature contour plot has an asymmetric behavior which is more pronounced at the <span><math><mi>x</mi></math></span>-direction due to the more accumulation of the non-locality effect. In fact, the silicon is thermally isotropic and so the non-symmetric behavior is attributed to the geometry of the device and the existence of non-locality parameters at <span><math><mi>x</mi></math></span> and <span><math><mi>y</mi></math></span> directions.

Because of this, though there are various forms of correlations or models for liquid film thickness in annular flows, their application ranges are limited. To broaden the applicable ranges, this study presents a novel model to predict liquid film thickness in vertical upward annular flow, derived from a one-dimensional force balance analysis. The model is derived from a first-principles force balance, linking film thickness to interfacial shear, wall shear, and gravitational forces. This mechanistic foundation enhances physical interpretability compared to purely empirical fits. In the proposed model, the influence of the interfacial inertia ratio on film thickness was found to be more pronounced compared to that of the Reynolds number ratio. Additionally, the impact of pipe diameter on film thickness was integrated into the model by validating its predictions against experimental data.
