查询词典 convection

The Sun's meridional circulation is a massive flow pattern within the Sun that transports hot plasma near the surface from the solar equator to the poles and back to the equator in the deeper layers of the convection zone, similar to a "conveyor belt".

太阳的经向环流，是在靠近太阳的运输，从太阳赤道面的极点和回在对流区，类似"传送带深层赤道热等离子体的大规模流动模式"。

To some extent, the nucleate boiling and the two-phase forced convective heat transfer through the liquid film always co-exist in the saturated nucleate boiling zone and two-phase forced convection zone. The liquid fill-ratio, input power and content of the non-condensable gas exert significant influence upon the start-up performance and the heat transfer performance of LHP.

并且在饱和核态沸腾区与两相强制对流区内，总是在某种程度上同时发生着核态沸腾区与两相强制对流液膜传热；充液量、输入功率及其不凝性气体的含量对回路热管的起动性能和传热性能部有很大的影响。

The simulation floating zone modelwith zero temperature gradient in the middle of the hot rod is proposed to simulate thehalf part of the full floating zone convection,since the temperature gradient in the middleof a full floating zone approaches zero.

根据加热方式的不同，可以将半浮区液桥分为通常半浮区液桥模型、模拟半浮区模型以及改型半浮区模型。通常半浮区液桥模型，液桥热端材料一般选择为金属材料，使得热端温度分布均匀。液桥产生热毛细对流时，在液桥热端内侧存在较大的轴向温度梯度。而在全浮区热毛细对流中，浮区中间的轴向温度梯度在对称条件下应该接近于零。

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

And then one day, he made and incredible discovery convection in water and food.

第2天，他做了一个不可思议的发明：可以传送水和食物。

Now that we have some heat, we can use this to cause convection.

既然我们有了一些热，我们就可以用这些来产生对流。

Therefore,the study of the numerical solution method for convection diffusion problems is important in theoretical and practical.

因此，研究对流扩散方程的数值解法有很重要的理论和实际意义。
