摘要
为了解横向磁场作用下环形液池内热毛细-浮力对流的基本特性,利用有限体积法对磁场强度分别为0、0.3T和0.5T进行了三维数值模拟。结果表明:当温差分别为5K、10K时,无磁场条件下,对流为稳态流动,在外加磁场的条件下,随着磁场的增加,对流失去稳定性,变为规则的振荡对流;进一步增大磁场,对流转变为无规则振荡对流。
In order to understand the basic characteristics of thermocapillary-buoyancy convection in the annular flu- id pool under the effect of transverse magnetic field, the finite volume method was used to simulate the magnetic field strength of 0, 0.3T and 0.5T, respectively. The results showed that when the temperature difference was 5K and 10K respectively, the convection was steady flow under the condition of no magnetic field. With the addition of magnetic field, the convection lost its stability and becomes regular oscillating convection. With increasing magnetic field, con- vection became ilTegular oscillatory convection.
