摘要：本文利用CATIA软件建立WD615.67A柴油机的气道-气门-气缸的三维几何模型,然后采用PRO-SURF、PRO-AM对几何模型重建表面及划分网格。应用所建立的模型研究在发动机不同气门升程时,对缸内流场的影响。
关键词： 气道-气门-气缸;;三维几何模型;;气门升程;;流场
Abstract: In this article,the CATIA is used
to build the intake passage-valve-cylinder three-dimensional model of the WD615.67Adiesel
engine.Afterwards,reconstructs surface and meshes grid to the model using the
PRO-SURF and PRO-AM.Analysis is done for the influence of flow field in
different valve lift using the new model.
Keywords: Passage-Valve-Cylinder;Three-dimensional
Model;Valve Lift;Flow Field
