Van der Waals Frictional Drag induced by Liquid Flow in Low- Dimensional Systems [PDF]
, 2008 We study the van der Waals frictional drag force induced by liquid flow in low-dimensional systems (2D and 1D electron systems, and 2D and 1D channels with liquid). We find that for both 1D and 2D systems, the frictional drag force induced by liquid flow

Viscometer using drag force measurements [PDF]
Review of Scientific Instruments, 2011 A robust and precise viscometer using the forces exerted by a laminar flow inside a small duct is presented: the force is measured on a long cylindrical sensor dipped into the flow. Two devices of respective volumes 1.4 and 0.031 ml have been realized, demonstrating that the technique is usable with small fluid volumes.

A Nnumerical Study of Drag force for Optimist Dinghy on Flat Water
MATEC Web of Conferences, 2018 This study investigates numerically the drag force on the Optimal dinghy, which is one of the official classes of international sailing regatta. The drag force is affected by the forward and backward tilt angles and the heels angles. The results revealed

NUMERICAL SIMULATION ON REAR SPOILER ANGLE OF MINI MPV CAR FOR CONDUCTING STABILITY AND SAFETY
Jurnal Ilmiah SINERGI, 2019 Spoiler attached on the rear part of a car can generate drag force and negative lift force, called downforce. This drag force can increase air resistance to the car, meanwhile, a negative lift force can improve the car’s stability and safety.

Long-span Suspension Bridge Flutter Analysis with Drag Force Effects [PDF]
Journal of Applied and Computational Mechanics, 2021 The paper investigates the influence of the drag force onto the flutter velocity and frequency of the Akashi Kaikyo Bridge. Finite element analyses were run in ANSYS by combining unsteady lift and moment actions with: (a) unsteady drag, (b) steady drag, (

Collective Ion Drag Force [PDF]
Plasma Physics Reports, 2019 The forces acting on the ensemble of dust grains in a plasma flow are analyzed. It is shown that the nonreciprocal character of the forces results in the appearance of an ion drag force, which depends on the intergrain distance. Results of calculations for two grains and an unbounded hexagonal lattice are presented.

Colloids dragged through a polymer solution: experiment, theory and simulation [PDF]
, 2007 We present micro-rheological measurments of the drag force on colloids pulled through a solution of lambda-DNA (used here as a monodisperse model polymer) with an optical tweezer.

On the rise and fall of a ball with linear or quadratic drag [PDF]
, 1999 We review the problem of a vertically thrown ball, with a drag force which is either linear or quadratic in the speed. It is stressed from the outset that these two types of drag correspond to specific ranges of the Reynolds number ...
