On dynamic stability of drill strings in a supersonic gas flow
In this work stability of the drill string nonlinear dynamics, complicated by the effect of an external axial load, initial curvature of the drill string, geometric nonlinearity and the influence of a supersonic gas flow as a circulating medium is studied. The drill string is modelled as a rotatin...
