Examples
- The scouring velocity of the molten steel against roll core is the highest and lower when the pouring angle is 15 and 90 , respectively
浇注倾角为15时，钢液对辊芯的冲刷速度较大，而浇注倾角为90时，钢液对辊芯的冲刷速度较小。 - If we change the aspect ratio ( a ) solely , an optimal reductive effectiveness of the mc can be gotten when a equals to 2 . 0 we obtained the correlation between the inlet gas velocity and other non - dimenional factors , which will be helpful to the practical application
利用模拟的结果，我们找出了使熔体内热毛细对流得到最佳抑制所需的气流冲刷速度和几个无量纲参数的关系式。这无疑对将来实验及工程上的适用有一定的指导意义。 - The results show : the reductive effectiveness is associated with the inlet gas velocity for a given conditions . by choosing the optimal gas velocity , which may be determined by an obtained correlation which was acquired by our result , the best reductive effectiveness of marngoni convection can be achieved
结果表明：硅熔体热毛细对流抑制程度和气体冲刷速度有着密切联系，合理的选择气流冲刷速度，可以使给定条件下的熔体热毛细对流减弱到一个最佳程度。 - The value of inlet gas velocity decreases and the reductive effectiveness of the mc increases when only decreasing the value of channel width . by changing the marangoni number alone , we found that the less the marangoni number , the less the needed inlet gas velocity and the better the reductive effectiveness of the mc
随着的增大，要想达到热毛细对流的最佳抑制，所需要的气流冲刷速度反而越小；但抑制程度随着值的增大有一个先增加再减小的过程，当为2时抑制程度达到最佳。 - The physical and mathematical models are founded . numerical simulation of marangoni convection in the liquid bridge and gas channel was performed by employing the primitive variable method and using galerkin finite element method , which is applied for discretization of non - dimensional governing equations and boundary conditions . the relationship between the suppressing status of mc in the liquid bridge and the inlet gas velocity or the channel width is obtained , and the suppressing status of some kinds of marangoni numbers ( ma ) or size ratios of liquid bridge a is analyzed
采用原始变量法，用galerkin有限单元法对无量纲控制方程及边界条件进行离散后，数值模拟了微重力条件下半浮区硅熔体及气体流道内的marangoni对流，得出了无量纲气流冲刷速度及流道宽度变化和熔体内热毛细对流抑制程度的关系，进而分析了不同的无量纲参数ma数和不同熔体几何尺寸比a下热毛细对流抑制情况。
