运用数值模拟具有能模拟各种不同边界条件的优势，还对非对称来流条件下形成的立轴旋涡进行了模拟。

Taking the advantage of numerical simulation that can simulate the different types of boundary conditions, the vertical vortex induced by the asymmetric initial flow is simulated too.

非对称的设计正好兼顾了功能上的分区，并在内部处理达到设备户外作业时能更好的防雨水等要求，体现产品的工业和力量感。

Asymmetric shape precisely serves the task of functional segmentation. In addition, the product has good waterproof property for outdoor works, giving the product a look of industry and power.

非对称流设计，管程与壳程容积不相同，(壳容积最大能达到管容积的4.2倍)，满足多种复杂工况。

Asymmetric design, products with different cubage between the length of tube and shell (cubage of the shell is 4.2 more than the tube), meet the complex requirement of project. to.

If we can do that, we'll end up with a symmetric nonpolar molecule.

如果我们能这样做，我们就能得到那些对称非极性的分子。
