grid type extraction valve

In the paper, a method of testing the stripe center in the inspecting system with grid-structured-light in that we can obstain some properties on image is put forward.

介绍了在光栅型结构光检测系统中,为了确定图像的某些特征而对光条中心的确定方法进行了研究。

In order to study the mixing and flow-uniforming effect of the grid-shaped mixer and turning vanes,the computational fluid dynamics(CFD)software is used to simulate the inlet flue duct of SCR system.

采用计算流体力学仿真软件对烟道中的流态进行了仿真,结果表明,格栅型混合器的使用能够增强气体径向混合,改善烟气与氨气混合的均匀程度;在烟道转弯处加入导流板可以明显减少出口速度分布偏差。
