Drag Coefficients of Viscous Drops

Fluids Engineering, 2000
Abstract We have used a finite-difference scheme to solve the Navier-Stokes equations for the steady flow inside and outside viscous spheres in a fluid of different properties. Hence, we obtained the hydrodynamic forces and the steady-state drag coefficient of the spheres. The computational technique we have used enables us to extend the

Drag Coefficients of Locomotion Over Viscous Soils

Journal of the Soil Mechanics and Foundations Division, 1960
To determine drag of wheel or track moving through mud, concepts of hydrodynamics pertaining to incompressible viscous fluids may be applied; problem is one of viscous flow around partially submerged object; variation in pressure causes bulldozing effect in front of wheel, and wake behind wheel; pressure drag may be reduced by streamlining wheel ...

Field determination of conductor drag coefficients

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract Electrical conductor drag coefficients are normally determined by wind tunnel tests. The effective conductor drag coefficients derived from measuring actual conductor wind loads experienced in operating transmission line structures do not correlate well with the wind tunnel results.

Swell and the drag coefficient

Ocean Dynamics, 2015
Simultaneous measurements of waves and turbulent fluxes were collected from a moored surface buoy in the Philippine Sea. Waves were partitioned into their wind sea and swell components, and the ratio of swell to wind sea energy was used to assign a swell index. The 10-m neutral drag coefficient was calculated using the eddy correlation method.

Drag Coefficient Estimation in Orbit Determination

The Journal of the Astronautical Sciences, 2011
Drag modeling is the greatest uncertainty in the dynamics of low Earth satellite orbits where ballistic coefficient and density errors dominate drag errors. This paper examines fitted drag coefficients found as part of a precision orbit determination process for Stella, Starlette, and the GEOSAT Follow-On satellites from 2000 to 2005.

Minimizing Drag Coefficients Using Bezier Technique

ASME 1992 International Computers in Engineering Conference: Volume 1 — Artificial Intelligence; Expert Systems; CAD/CAM/CAE; Computers in Fluid Mechanics/Thermal Systems, 1992
Abstract Optimizing the profile design of a vehicle body for minimum drag coefficient can have a beneficial impact upon the vehicle performance, energy conservation, and exhaust gas emissions. An interactive technique based on the fundamental concepts of Bezier equations was utilized to develop the body profile and its corresponding drag

Particle drag coefficients in turbulent fluids

Chemical Engineering Science, 1998
Abstract An accurate estimation of particle settling velocities, and/or of particle drag coefficients, is required for modelling purposes in many industrially important multiphase processes involving the suspension of millimetre and sub-millimetre size particles in a liquid phase.

Drag Coefficients for Irregular Fragments

1988
Abstract : Drag coefficients for irregular fragments were determined for 96 fragments in a vertical wind tunnel at Mach numbers of approximately 0.1. Correlation of drag coefficient with the maximum-to-average presented area ratio is presented. A method for approximating the whole drag curve is also given.
