摘要: 采用ANSYS/CFX对减振器在深井工作时的流场,尤其对心轴颈部处的流场进行了数值模拟计算,得到了壁面剪切应力与钻井液黏性系数的关系。数值模拟结果表明,在设计减震器结构时,选择合理的颈部过渡圆角,可以有效地调整流场特性,避免裂纹的产生。

Abstract: ANSYS/CFX was adopted to analyze the rotating flow field around the rotating shock absorbers, especially the flow field near to the neck area, the relationship of the wall shear stress and viscosity parameters of drilling fluid was been obtained. As a result, reasonable round angle can be designed to adjust flow pattern effectively and the crack can be avoided.
