本研究提出了一个三维流格模型(FLM)的制定和验证与应用的湿-热-化学(HTC)模型的水分传输和热传递在水泥材料的分析。FLM是一种与细观力学模型(如晶格离散颗粒模型)相关联的离散输运模型。这使得能够在材料表现出内在异质性的长度尺度上模拟传输现象。HTC理论公式是基于质量和能量守恒定律,使用湿度和温度作为主要变量,并明确考虑各种化学反应,例如,水泥水化和硅灰反应,作为内部变量。在这项工作中,HTC配方扩展到包括温度对吸附等温线的影响。的FLM解决方案进行了比较与HTC模型和实验数据的连续有限元实现,从文献中,整体协议证明了所提出的方法在重现现象,如水泥水化,自干燥和温度依赖性水分干燥的可靠性。
This study presents the formulation and validation of a three-dimensional Flow Lattice Model (FLM) with application to the Hygro-Thermo-Chemical (HTC) model for analysis of moisture transport and heat transfer in cementitious materials. The FLM is a discrete transport model formulated in association with meso-mechanical models, such as the Lattice Discrete Particle Model. This enables the simulation of transport phenomena at the length scale at which the material exhibits intrinsic heterogeneity. The HTC theoretical formulation is based on mass and energy conservation laws, written using humidity and temperature as primary variables, and considering explicitly various chemical reactions, for example, cement hydration and silica fume reaction, as internal variables. In this work, the HTC formulation was extended to include the effect of temperature on the sorption isotherm. The FLM solutions were compared with those of a continuum finite element implementation of the HTC model and experimental data available from the literature; the overall agreement demonstrates the reliability of the proposed approach in reproducing phenomena such as cement hydration, self-desiccation and temperature-dependent moisture drying.
