The flow structure displayed a reverse jet current in the lateralcavity and white corrosion on the lateral enlargement surface.
试验细部结构特征，发现侧空腔内的反射回漩流和突扩弧形面上的白色蚀带。
2
Simultaneity lateralcavity and bottom cavity are linked each other, which prevent cavitation damage of sidewalls and soleplates.
侧空腔畅通并直接和底空腔相连，对侧墙和底板都起到了很好的保护。
3
Apply the weighted surface parameter equation to fit the algorithm of cavitylateral surface, and realize the cavity surface construction of radial parting mold of meridian tire.
