双语例句
- The impeller comprises a blade and a hub, wherein the blade is connected with the hub of the impeller through a level shaft in a shape of a bended arch.
所述叶轮包括叶片和轮毂，所述叶片与叶轮轮毂通过一弯拱形水平轴相连。 - The fully three-dimensional Reynolds-averaged Navier-Stokes equations in conjunction with the standard two-equation k-ε turbulence closure are adopted to analyze the influence of wall roughness on the hydraulic performance of axial-flow pump, inclusive of impeller, guide vanes casing and hub.
采用全三维雷诺时均Navier-Stokes方程和标准κ-ε湍流模型，数值模拟了包括叶轮、导叶、泵壳和轮毂等过流部件壁面粗糙度对轴流泵水力性能的影响。 - Taking fan noise as a target, impeller diameter, hub ratio& speed as design variables, the fan noise can be reduced as low as possible by optimization design program.
以风机噪声为目标，取叶轮直径、轮毂比及转速为设计变量，通过优化设计程序，可以使所设计的风机噪声尽可能小。 - The instantaneous water impact caused by impeller rotation acceleration led to a great stress concentration on the impeller hub, and the maximum equivalent stress increased in a geometrical progression.
叶轮旋转加速度带来的瞬时水流冲击对叶轮轮毂处造成了更大的应力集中，最大等效应力呈现几何倍数增长。 - Finally, carring on the modal analysis to the impeller, we obtain mode of vibration distortion chart of hub and vibrational frequency and the distortion situation through the vibration-distortion chart of hub.
最后，对叶轮进行模态分析，得到轮毂的振型变形图。 - In different conditions, with the increasing of flow rate, the flow in impeller and diffuser became worse; from hub to shroud, flow turned more complexity.
结果发现，不同工况下，随着流量的增加，叶轮和扩压器部分的流动变差；由盘侧至盖侧，离心压缩机内部流动逐渐变得紊乱。
