详细介绍了阶梯形零件冷挤压工艺的制订过程,根据实践经验总结了其冷挤压模具设计的结构特点。
Through a study of the phenomenon of boundary layer transition on a plate at zero pressure gradient,the authors have concluded that the influence of the complexity of the transition flows on the boundary layer of a flow field should not be neglected.
通过对零压力梯度的平板转捩现象的研究得出以下的结论:转捩流动的复杂性对流场边界层的影响不容忽视;M-L转捩模型能比较准确地预测转捩的发生和发展过程,在高湍流度下使用全湍流模型来模拟转捩流动的误差较小。
