Structural Design and Flow Field Analysis of Rotating Shock Absorbers in Deep Well Drills
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.
