Enhanced Drag in Pipe Turbulent Flow by an Aqueous Electrolyte: an Electroviscous Effect [PDF]

open access: yes, 2009
Drag enhancement is reported for turbulent pipe flow of aqueous electrolyte solutions. No electroviscous effect was obtained with laminar flow. Nor was any unusual pressure drop observed for laminar or turbulent flow of non-electrolyte aqueous solutions ...

Superhydrophobic surfaces and their potential application to hydrodynamic drag reduction

open access: yes, 2014
Superhydrophobic surfaces appear frequently in the natural world, for example allowing insects to respire underwater and plants, such as the lotus leaf, to have self-cleaning properties.

SUPERHYDROPHOBIC SURFACES FOR DRAG REDUCTION

open access: yesIstituto Lombardo - Accademia di Scienze e Lettere - Rendiconti di Scienze, 2014
Properties of superhydrophobic materials are examined in light of their possible use for drag reduction in naval applications. To achieve superhydrophobicity a low-surface-energy material must be structured so as to minimize the liquid-solid interactions.

Computational Analysis of Turbulent Flow over a Bluff Body with Drag Reduction Devices

open access: yes, 2020
Reducing aerodynamic drag of heavy trucks is crucially important for the reduction of fuel consumption and hence results in less air pollution. One way to reduce the aerodynamic drag is the deployment of drag reduction devices at the rear of trucks and ...

Comparative computational analysis of drag-reducing devices for tractor-trailers [PDF]

open access: yes, 2008
Constant rise in fuel price in recent times has caused manufacturers of heavy commercial vehicles (HCV) to turn to efficient aerodynamic design of trucks, wagons, tractors as well as trailers.

Agitator Tank Device and Drag Reduction Agent Evaluation

open access: yes, 2008
The device that consists of tank and disk agitator for evaluation drag reduction agents (DRA) was established. The effect of DRA was defined by testing the changes of agitator torque that drives the disk rotation.

Investigation of relationship between drag and lift coefficients for a generic car model [PDF]

open access: yes, 2014
The paper presents a study of aerodynamic characteristics of a car, which has the simplified geometric shape, so called Ahmed body. Flow around the body and the influence of its rear slant angle on drag are widely studied by numerous researchers. However,

Drag Reduction of Complex Mixtures /

open access: yes
"Drag Reduction of Complex Mixtures discusses the concept of drag reduction phenomena in complex mixtures in internal and external flows that are shown experimentally by dividing flow patterns into three categories.

Drag reduction on a simplified 3D bluff body

open access: yes, 2015
A complete flow control over road vehicles is difficult to achieve because of different phenomena occurring in flow evolution, i.e. the wheel rotation and ground effect deeply influence the flow features.
