摘要�为更好地得到液态金属的流动和传热特性,模拟了液态金属流体镓� Ga�自然对流流动和传热过
程. 采用单流体模型研究液态金属流体 Ga 的流动特性和传热机理,考虑边界条件对自然对流的影响,选用
合适的边界条件进行了模拟. 结果表明,该工况下的传热以导热为主,速度矢量是顺时针旋转分布,并与实验
数据较好吻合. Gr 数对液态金属 Ga 自然对流影响的数值模拟表明,随着 Gr 的增加,液态金属的换热逐渐以
对流换热为主.

Abstract To better understand the heat-transfer character and flow of liquid gallium a natural convection
flow of liquid gallium was numerically simulated by using single phase method on the heat transfer of liquid
gallium in a two dimensional enclosure. The effects of boundary condition and Grashof number on the flow and
the convective heat transfer behavior are investigated
