A hybrid numerical approach, combining finite volume methods and random walk simulations, is utilized to assess how geometric parameters (power, curvature, and periodicity) affect porosity, tortuosity, specific surface area, and diffusion behavior at both macro and micro scales. In the continuum regime, the effective diffusion coefficient is primarily influenced by porosity and tortuosity. Structures with odd power values show reduced pore connectivity and porosity with increasing power or curvature, leading to decreased diffusion coefficients. Even power values result in dual-pore configurations that maintain higher porosity and specific surface area, with diffusion behavior mainly affected by throat dimensions. At the microscale, increasing periodicity reduces pore and throat sizes, prompting a transition from continuum to non-continuum transport behavior. The study also analyzes the sensitivity of the effective diffusion coefficient to pressure and temperature. In the continuum regime, the diffusion coefficient increases with decreasing pressure, while in the Knudsen regime, it becomes pressure-independent. Elevated temperatures enhance the diffusion coefficient across all regimes, with a more pronounced effect in the continuum regime. These findings provide a framework for optimizing triply periodic minimal surface-based porous media to improve gas-phase diffusion, with practical implications for enhancing the efficiency of solar thermochemical reactors.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"252 ","pages":"Article 127434"},"PeriodicalIF":5.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144490732","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 addition, for horizontal flow, there is a different heat transfer performance between the top and bottom of the tube complicating the prediction even further. In this work, the prediction capability of existing correlations and several correction factors are evaluated based on experimental heat transfer data on supercritical refrigerants flowing in heated horizontal tubes.

To address this issue, the 3D electrochemical-thermal model used in this study is developed to analyze the electrochemical and thermal behavior of a commercial large-format NMC622 battery cell under constant-power discharge conditions. In more detail, a multiphysics numerical model capable of coupled analysis of charge transport, mass transport, and energy balance phenomena occurring during battery operation has been developed. Through this, a foundation is established for easily identifying electrochemical-thermal behaviors that are difficult to analyze experimentally. Based on the completed numerical model, constant-power analysis, rather than constant-current analysis, is conducted to simulate the power control process of an actual electric vehicle. Various heat generation mechanisms—including reaction heat, activation heat, electronic ohmic heat, and ionic ohmic heat—are thoroughly analyzed. The developed three-dimensional model is experimentally validated with respect to voltage, current, and temperature. Based on the validated model, the thermal behavior during discharge is analyzed. It is found that in the commercial cell considered in this study, ionic ohmic heat dominates during high-power discharge, while reversible reaction heat dominates during low-power discharge. Detailed heat analysis shows that most heat is generated in the two electrodes, with the negative electrode contributing the most. Due to reaction heat, an endothermic reaction occurs in the negative electrode at the early stage of discharge. Furthermore, the analysis of activation heat confirms that a significant activation overpotential develops in the positive electrode near the end of discharge. The localized heat generation is greater in the side surface (thickness direction) rather than on the front surface of the cell, as confirmed by simulation. Finally, the effect of cell geometry is investigated. The results show that as the electrode becomes thinner, lithium-ion transport becomes more efficient, leading to improved electrochemical and thermal performance.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"252 ","pages":"Article 127435"},"PeriodicalIF":5.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144480209","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 work, we propose a semi-empirical model to predict the thermal conductivity profile as a function of distance to a boundary, to help explain experimental observations. The model is based on a geometrical suppression in the phonon mean free path and accounts for phonon transmission at the boundary. Calculated excess thermal boundary resistances, extracted from spatially dependent thermal conductivities with a Gibbs excess approach, are well-matched with predictions from the Landauer formalism when considering heat flow normal to the boundary. This agreement holds for different material systems and over temperature. The excess thermal resistance is thus expected to represent well the theoretical boundary resistance.
