inlet angle

The inlet film thickness was defined by analyzing the inlet zone, and the influence of unsteady variables such as strip tension stress, rolling speed and inlet angle on inlet film thickness was considered.

考虑了非稳态变量如带张力、轧制速度、入口角等因素对入口油膜厚度的影响，同时还分析了入口油膜厚度的频率响应情形。

In the meantime , the effect of air inlet angle on particle deposition was also researched.

同时, 研究了不同气流进口角对粒子沉积状况的影响.

In comparison with 30 ° air inlet, the generated vortexes are fewer, weaker and nearer to the air inlets when the inlet angle is 45 ° along the axial cross section.

与30°进气道相比，沿轴向横截面上45°进气道所形成的回流区向进气道一侧偏移，回流区区域减少，强度减弱。
