Drag and Torque on Locked Screw Propeller
TransNav, the International Journal on Marine Navigation and Safety of Sea Transportation, 2014 Few data on drag and torque on locked propeller towed in water are available in literature. Those data refer to propellers of specific geometry (number of blades, blade area, pitch and skew of blades). The estimation of drag and torque of an arbitrary propeller considered in analysis of ship resistance or propulsion is laborious.

Torque & Drag Analysis Using Finite Element Method
Modern Applied Science, 2011 The calculation and analysis of torque and drag play an important role in drilling and well design. Different models (soft, stiffness, mixed and finite element) have been used to calculate the torque and drag. This paper introduces a practical FEA (Finite Element Analysis) model of the drill string which can reflect working behavior, including ...
