OM exhibits distinct characteristics compared to inorganic matter in terms of pore structures and fluid-solid interactions. Recent studies have revealed complex transport phenomena within shale pores. However, the mobility of oil within OM remains poorly understood. In this study, oil depletion experiments were conducted using shale and tight sandstone cores to evaluate the influence of OM on flow behavior. Subsequently, a novel pore network modeling framework was developed, which integrates liquid compressibility, pore deformation, and the interaction between OM and oil. The proposed model was validated by comparing the simulated flow rates to those from the experiments. By employing pore network models with varying pore structures, the oil depletion process was simulated to quantify oil mobility within OM and assess its contribution to the overall production performance. When considering the interaction between OM and oil, the contribution of OM to oil production is significantly higher than the fraction of organic pore volume. Increasing OM content and porosity improve the contribution of OM. Neglecting the interaction leads to an underestimation of the OM contribution. Among different OM distribution models, the layered-OM model shows the highest pressure depletion rate, while the single-bulk-OM model exhibits the lowest rate. High clay content slows OM deformation and delays the associated increase in pore pressure, while also inhibiting pressure release within OM. This study provides fundamental insights into the role of OM and microstructural properties in shale oil mobility.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"260 ","pages":"Article 128441"},"PeriodicalIF":5.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075848","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 work fabricated aluminum surfaces featuring anisotropic microstructural arrays at sub-millimeter scale using nanosecond laser ablation, followed by global superhydrophobic modification of the microstructural metal substrates via an immersion method. By establishing a visualization experimental platform, conducting condensation-frosting experiments on superhydrophobic surfaces with typical topologies, including cylinders, triangular prisms and cuboids.

This revealed the multifaceted influence mechanisms of microstructural topology on multi-scale droplet dynamics and surface frosting process. Results demonstrate that sub-millimeter scale microstructures influence frequency of coalescence, coalescence-induced bouncing and multi-droplet coalescence of small-scale droplets during the initial stage of condensed droplet clusters growth, thereby affecting droplet clusters size distribution. Its anisotropy subsequently influences the spatial distribution of large-scale droplets during the later growth stage.

For plastic films, widely used in packaging and comprising mostly polyolefins, mechanical recycling is not practical, hence the interest in chemical recycling. Dissolution/precipitation recycling can recover polyolefins for re-use, with energy needs and emissions much lower than pyrolysis. The dissolution of polyolefins is key to this recycling process, however, the underlying phenomena which govern the dissolution of semicrystalline polymers are little studied. To address this gap in knowledge, the swelling and dissolution kinetics of high-density polyethylene (HDPE) films are investigated here. Experiments are designed to obtain the time evolution of HDPE dissolved mass and degree of crystallinity. A mathematical model is developed to describe the swelling and dissolution of semicrystalline HDPE based on the transport phenomena and thermodynamics governing the process. Experimental data are used to validate the model and to obtain values for the two key fitted parameters, decrystallization constant and disentanglement rate. The detailed information provided by the model, spatial and temporal composition and solvent diffusion, reveals the molecular mechanism of HDPE dissolution. A parametric analysis is performed using the validated model to simulate dissolution phenomena at varying conditions, including initial degree of crystallinity and film thickness. These insights on polyethylene dissolution facilitate the design of more energy efficient and environment-friendly dissolution-precipitation recycling processes.

However, droplets in natural environments are rarely pure but usually contain dissolved solutes, making their freezing behavior more complex.

Here, we systematically investigate the freezing characteristics of NaCl solution droplets with different concentrations under substrate temperatures above and below the eutectic point, and identify the key stages and pivotal points that characterize saline droplet freezing. For saline droplets with lower concentrations (<em>ω</em> &lt; 23.3%) below the eutectic temperature, the freezing process involves the ice crystals growth and the hydrate precipitation, with both onset and completion precisely identified. In higher-concentration droplets (<em>ω</em> &gt; 23.3%), the process proceeds via sequential NaCl crystallization and subsequent hydrate formation, and a temperature rise is observed on the temperature–time curve during the hydrate precipitation stage. The time fraction associated with each freezing stage are quantitatively compared among different freezing types. Then the factors governing hydrate-precipitation kinetics are examined under substrate temperatures below the eutectic point. Both decreasing temperature and increasing salinity accelerate the hydrate precipitation time.

Additionally, there is a thermo-electric generator (TEG) connected to each PV unit.

The largest temperature reductions are achieved by using inlet temperature pulsations among the different approaches, especially at the lowest Re, which is roughly 8.7 °C at Re=100 and 4.2 °C at Re=500 for unit A, while these values drop to 7.4 °C and 5.3 °C for unit B.
