That's a Drag: The Effects of Drag Forces

open access: yesUndergraduate Journal of Mathematical Modeling: One + Two, 2009
Drag is a force that opposes motion due to an object's shape, material, and speed. This project defined what drag force is, derived the governing equation for drag and listed some applications of drag forces.

A Dynamic Model of Drag Force for Catalytic Micromotors Based on Navier–Stokes Equations [PDF]

open access: yesMicromachines, 2018
In past decades, considerable advances have been achieved in micro and nanomotors. Particular attention has been given to self-propelled catalytic micromotors, which have been widely used in cell separation, drug delivery, microsurgery, lithography and ...

Drag force for a burning particle [PDF]

open access: yesCombustion and Flame, 2020
Abstract Fully-resolved simulations of a burning char particle are performed to understand the effects of chemical reactions on the drag force by using the ghost cell immersed boundary method. The momentum, heat and mass transfers at the interface are all considered.

Drag of a cylindrical object in a two-dimensional granular environment [PDF]

open access: yesEPJ Web of Conferences, 2021
The drag of a cylindrical object in a two-dimensional granular environment is numerically studied. It is found that the drag law is fitted by the sum of the yield force and the dynamic force, the latter of which is reproduced by a simple collision model.

Drag Forces in Classical Fields [PDF]

open access: yesPhysical Review Letters, 2010
Inclusions, or defects, moving at constant velocity through free classical fields are shown to be subject to a drag force which depends on the field dynamics and the coupling of the inclusion to the field. The results are used to predict the drag exerted on inclusions, such as proteins, in lipid membranes due to their interaction with height and ...

Modeling of the Drag Force in Polydisperse Gas–Solid Flow via an Efficient Supervised Machine Learning Approach

open access: yesApplied Sciences, 2023
Most granular flow in nature and industrial processing has the property of polydispersity, whereas we are always restricted to using the monodisperse drag force model in simulations since the drag force model with polydispersity is difficult to establish.
