- 结果表明抱辊偏心对变形抗力有影响,辗扩工艺具有不完整的三角形速度场。
The results show that eccentricity of ring holder affects the deformation resistance that the velocity field is a non-perfect triangular one. - 在设计点附近作了沿叶高效率分布及动叶进、出口速度三角形的测定。
The efficiency distribution along blade span and the inlet and outlet velocity triangle measurement of rotor blades were made around the designing point. - 本文首先介绍了风扇的工作原理,包括基元级的速度三角形、叶型和叶栅参数以及叶栅的空气动力学方程。
This paper explains the working principles of a fan, including velocities on an elementary stage, parameters of blade types and cascades and the aerodynamics formulas of cascades.
