查询词典 airflows

The results show that Prandtl mixing length theory predicts airflows better than zero-equation model provided by Chen,and that Prandtl mixing length theory is more reasonable than zero-equation model provided by Chen but Chen's model seems easier to converge from the analyses of their construction.

由于该模型应用起来非常方便，并且计算量比标准K-ε模型小很多，它逐步受到工程研究人员重视。2001年，该模型被Fluent公司采用，并在其商用CFD软件Airpak修回日期：2006 07 11中采纳，对其在国际暖通空调领域内的广泛使用起了推动作用。

Evaluates the zero-equation model provided by Chen based on CFD simulation of three typical airflows(forced convection,mixed convection and natural convection)in air-conditioned and ventilated rooms.

为了对Chen提出的零方程模型进行评价，研究了三种典型的空调通风房间气流组织工况(强迫对流、混合对流和自然对流)，同时采用Prandtl的混合长度理论和双方程K-ε湍流模型的计算结果作为比较。

It suggests that the horizontal momentum of the meso-cyclone was brought down to the surface by heavy rain. At the right edge of meso-cyclone the momentum and RIF have the same direction, the two airflows overlay together and make the wind increase, so damage wind occurred.

分析认为，弓状回波后部存在较强后部下沉入流，由于强降水的拖曳作用，将中层中气旋的水平动量带到地面，中气旋右侧动量的方向与弓状回波后部的强下沉入流方向一致，两者叠加，使地面风速加大，造成灾害性大风。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
