| 摘 要： | 为研究通道内空气热磁对流的流动规律,用数值模拟方法,研究了磁场作用下二维模型水平通道内的流动换热过程,获得了通道内的磁通密度分布和空气温度轴向分布,在此基础上,建立了一维通道内空气热磁对流的数学模型,就温度场和磁场的相对关系对水通道内热磁对流过程的影响进行了数值计算,获得了通道内不同温度场、磁场以及其不同相对位置下的通道空气流量,并讨论了磁极形状对空气流量及其变化的影响。

| Abstract: | In this paper, numerical study was performed on the flow and heat transfer of magneto-thermal convection in a two dimensions horizontal tube, distributions of magnetic flux and temperature field in the tube was presented, and further, mathematic model of one dimension magneto- thermal convection is constructed. Based on this model, numerical simulation was performed to study influence of the relationship between magnetic field and temperature field, volume flux of air was achieved under different temperature and magnetic field, and relative position, influence of the shape of the magnet head was also studied. |
