The efficiency of bioreactor lanfills depends on a homogeneous distribution of leachate in the waste body. Therefore, optimisation of leachate injection systems is a challenging issue for operators. Most studies have shown that surface Electrical Resistivity Tomography (ERT) can be a ... Mehr lesen
互层岩体台阶爆破中力学差异性较大的岩层影响了炸药能量的均匀分布,为了快速确定影响爆破效果的主控岩层的位置及台阶整体炸药单耗,采用数值分析的方式探讨了主控岩层对炸药能量分布特征的影响规律,实验结果表明:采用连续装药结构时力学差异性较大的夹层处质点运动速度更为集中,而间隔装药可改善台阶内速度场的分布均匀程度;由最小抵抗线原理分析发现主控岩层的厚度和力学性质是影响炸药能量传递方向的主要因素;在此基础上结合波阻抗原理,构建了考虑台阶岩体整体力学特性及各岩层局部工程特征的能耗分级体系,通过现场测试取得了良好的应用效果,验证了该方法的可行性 ... Mehr lesen
页岩储层水力压裂中的裂缝扩展行为直接影响裂缝网络形态与油气产能提升。本文基于 COMSOL Multiphysics 建立三维流固耦合压裂数值模型，模拟并分析了五类典型压裂情形：单一裂缝扩展、两簇裂缝扩展及互相干扰、三簇对称压裂、三簇完全压裂以及水平主裂缝与垂向天然裂缝相交的情形。本文首先介绍了耦合力学与孔隙流体动力学控制方程、材料与边界条件，然后引入室内实体实验参数作为模型校核（包括页岩破裂韧性、抗拉强度、弹性模量与渗透率等特性）。在 COMSOL 中采用损伤参数化的线弹性-弹塑性破裂捕捉策略，并结合能量释放率与临界应力强度因子判据来判定裂缝的起裂与扩展。数值结果显示 ...

Campi Flegrei (CF) is the largest active urbanized caldera in Europe, currently experiencing slow but progressive ground uplift and increasing seismicity since 2005. This deformation is marked by transient variations in uplift rates, with monotonic episodes lasting weeks to years. In ... Mehr lesen
Bitumen and asphalt durability is a critical concern in pavement engineering, particularly in the context of sustainability and carbon footprint reduction. Accurate prediction of the lifespan of these materials is essential for life cycle assessment (LCA) from cradle to grave. However, ... Mehr lesen
Geothermal energy systems require precise sizing to ensure efficiency and sustainability, particularly for probe fields and groundwater doublets. We present two specialized applications developed using COMSOL Multiphysics’ Application Builder, leveraging the Heat Transfer and Groundwater ... Mehr lesen
Reactive transport modelling in subsurface environments, such as geological disposal of radioactive waste, often requires complex coupling between transport phenomena and geochemical reactions. Traditionally, this coupling requires third-party tools such as iCP to link multiphysics ... Mehr lesen
Underground mines that employ the sublevel caving (SLC) method often suffer from significant levels of ore dilution due to the technique of extracting ore through gravity flow. When the ore is blasted and falls into drifts, it creates the drawpoints where Load-Haul-Dump (LHD) vehicles ... Mehr lesen
This study presents a model for simulating a subsurface pumped-hydro energy storage (battery) system. The model captures the coupling between fluid flow in an oil and gas type wellbore connected to a large hydraulic fracture embedded in a low-permeability reservoir. By integrating ... Mehr lesen
