纳米磁流体具有高靶向性和可控性，在药物靶向释放，磁分离以及微流控领域中引起广泛关注。磁流体是在基础流体如水、乙二醇等溶液中分散直径小于 20 nm 的磁性粒子，其作为一种新型的高传热性能的能量输送媒介，在其应用过程中传热性能是不可忽略的。国内外许多学者对磁性流体流动与强化换热机理进行了许多研究，取得了大量的研究成果。磁流体由于具有磁性和流动性，在外加磁场作用下，利用磁场调控能够有效增强换热效果。基于此本文在稳态条件下，利用磁场、流体和传热多物理场耦合方式，针对二维通道内磁性流体进行数值仿真计算，通过设置不同磁体组合、纳米流体体积分数和磁场强度研究磁流体的传热性能。 Read More
基于磁流体动力学与Maxwell方程组，建立微束等离子弧焊电弧的二维轴对称模型，应用COMSOL软件进行求解计算，得到了微束等离子弧焊的电弧温度场、流场、电流密度、电弧所受洛伦兹力以及工件表面电弧压力分布情况，并通过实验所拍摄的电弧形态对模拟的温度场加以验证。结果表明微束等离子弧焊电弧温度、等离子体速度与电弧所受洛伦兹力具有相同的变化趋势，均从阴极到阳极先增大后减小，从电弧中心逐渐向四周降低，最大值出现在喷嘴内部中心区域；电弧电流密度在阴极下端面取得最大值，在工件上表面取得最小值，且从阴极到阳极减小速度呈一个先减小后增大再减小的趋势；电弧压力与等离子体流速径向变化相同 ...

透明导电薄膜是柔性触摸屏、太阳能电池、透明加热器等现代设备中的关键部件。基于模板法制备的透明导电薄膜没有结电阻，具有高光学透明度及低薄层电阻，特别适用于透明加热器中。这种透明导电薄膜的电学、光学性能及稳定性与其中随机金属线网络的几何结构有着紧密关联。由于随机的金属线网络尺寸小至微米甚至纳米级，只能通过高分辨率的红外显微镜研究薄膜电加热时的温度分布情况，而其中电流的分布则要通过数学方程计算。因此，需要开发一种电-热耦合模型，探究透明导电薄膜在电加热过程中的电流及温度的分布情况，分析薄膜电加热性能与金属线网络几何结构的关系 ... Read More
