| 摘 要： | 磁场能强化磁性液体的自然对流传热。为了准确测量磁场对磁性液体强化自然对流传热的贡献,设计制作了一个由均匀磁场和均匀梯度磁场矢量叠加合成的新磁场。在恒定温度梯度下,新磁场使磁性液体各处密度变化均等,各处自然对流传热变化均等。从而比较准确地测量了磁场引起的磁性液体自然对流传热系数的变化,为深入研究磁场强化磁性液体自然对流传热的效应提供了比较准确的测量手段。

| Abstract: | The natural convection transmitting heat in magnetic fluid can be strengthened by magnetic field.In order to accurately measure the contribution of magnetic field to this process,a new magnetic field is established which is composed of a uniform magnetic field and a uniform gradient magnetic field.Under the condition of even temperature,the new magnetic field brings about an even change of density and an even change of natural convection transmitting heat.The experiment has accurately measured the changes of natural convection transferring heat in magnetic fluid,and has provided a good method of accurate measurement. |
