Drag modeling
Planning high-angle wells involves diverse areas; one of the most important of these areas is torque and drag (T&D) management. Not only could uncontrolled T&D cause various drilling problems like drill string (D/S) failures, casing wear, stuck pipes, and slow rates of penetration but it could also entirely stop the drilling progress, if torque and/or drag exceed rig or string capabilities ...

The US and China are dragging dow...The parabolic drag model is not exact; but accurate enough for the purpose of performance calculation. A similar behavior is observed for the variation of drag coefficient versus lift coefficient. Drag polar is the plot (i.e., a mathematical model for the variations) of drag coefficient as a function of lift coefficient. Figure 3.3.A bubble-based EMMS/DP drag model for discrete particle methods is proposed, which considers the effects of sub-grid meso-scale structure on drag force by taking into account particle position and velocity information. By implementing the new drag model into the MP-PIC method, two different bubbling fluidized bed columns were simulated.Canopy Drag Model Assessment Emergent Canopies. The canopy drag model for emergent canopies, based on Equations (2)–(4) using the computed constricted cross-section velocity U c e m (see section Canopy Drag Model), was used to predict the drag force on a single canopy element in all experimental cases (Table 1).Drag is a gender-bending art form in which a person dresses in clothing and makeup meant to exaggerate a specific gender identity, usually of the opposite sex. …
