Experimental and Numerical Studies on Behavior of Rotating Drill Pipe Model in Uniform Flow

摘要

In this study, the underwater behavior of a drill pipe model rotating in uniform flow was investigated through experimental and numerical analyses. The hydrodynamic force acting on the rotating equipment of the drill pipe model was measured, and its coefficient was derived. The displacement of the drill pipe model was also observed and measured. The numerical estimation of the model's displacement was implemented by applying computational fluid dynamics and absolute nodal coordinate formulation.
