磁场、流体特性及几何参数对液态金属双扩散对流的影响OA北大核心CSTPCD
Effects of magnetic field,fluid properties,and geometric parameters on double-diffusive convection of liquid metals
磁场作用下导电流体热对流是当前研究的热点问题,本文采用高精度高分辨率的数值方法对二维腔体内液态金属双扩散对流进行直接数值模拟,研究了在水平或垂直磁场作用下,磁场强度、Prandtl数、Lewis数以及高宽比对流动和传热传质的影响.研究结果表明:磁场主要表现为对流动和传热传质的抑制作用.在相同强度下,水平磁场比垂直磁场的抑制作用更大,但在较弱磁场和较强磁场时,二者对传热传质的影响效果相近.对于不同方向和强度的磁场,传热传质效率总是随着Prandtl…查看全部>>
Thermal convection in conducting fluids under the influence of a magnetic field is a hot research topic.In this study,a high-precision and high-resolution numerical method is used to directly simulate the double-diffusive convection of liquid metal in a two-dimensional cavity.The study covers the effects of magnetic field strength(Ha),Prandtl number(Pr),Lewis number(Le),and aspect ratio on the dynamics of flow and heat/mass transfer under both horizontal mag…查看全部>>
