Torque and Drag Friction Model: Implemented Friction Factor Dependency of Temperature [PDF]
, 2016 Master's thesis in Petroleum engineeringWe investigated the friction factor dependency of temperature. “Friction factor” is a parameter in the calculations of torque and drag. Increased well reach is dependent on accurate torque and drag modeling.

Torque and drag in directional drilling : master's thesis [PDF]
, 2015 Prekomjerne vrijednosti torzije i natega mogu uzorkovati negativne posljedice na sam tijek izrade usmjerenih bušotina. Pretpostavka kod usmjerenog bušenja jest da su i torzija i nateg posljedica uglavnom trenja koje se javlja između niza bušaćeg alata i ...

From Instruction to Inheritance: Scaling Robot Learning Through Knowledge Circulation
Advanced Intelligent Systems, EarlyView.Robot learning moves from one‐way instruction toward knowledge circulation. Humans teach robots, robots teach one another, and robots share acquired skills with humans. This perspective connects teaching, embodiment, and learning architectures to explore how knowledge is inherited, adapted, and enriched across agents, opening a path toward scalable ...

Drag, lift and torque coefficients for ellipsoidal particles
, 2013 In this work, we want to verify the ability of the CFD code Ansys Fluent© to give an accurate prediction of hydrodynamic forces acting on non-spherical (Ellipsoids). We focus the present study only on the drag and lift forces and also on the pitching torque.
