Two and three-dimensional natural convection of liquid metal was studied both theoretically and experimentally. The effect of external magnetic field on convection was included. The direction of external magnetic field was found to suppress the rate of convection and the rate of heat transfer differently. The most effective direction was perpendicular to the heated and cooled walls. The least effective direction was parallel to the heated and cooled walls. These theoretical findings were experimentally confirmed afterwards. Three-dimensional Czochralski convection was also successfully simulated with a magnetic field.

对液态金属的二维和三维自然对流进行了理论和实验研究。考虑了外加磁场对对流的影响。外磁场方向对对流速率和换热速率的抑制作用不同。最有效的方向是垂直于加热和冷却的墙壁。最不有效的方向是平行于加热和冷却的墙壁。这些理论发现后来被实验证实了。用磁场成功地模拟了三维契诃夫斯基对流。
