On the drag and virtual mass coefficients in Biot’s equations

The Journal of the Acoustical Society of America, 1983
If the solid constituent of a fluid saturated porous medium is assumed to be subjected to a uniform oscillatory motion, Biot’s equations can be solved for the drag and virtual mass coefficients in terms of the resulting oscillatory motion of the fluid.

Drag Coefficients of Latticed Towers

Journal of Structural Engineering, 1986
Recent building codes require that wind loads be determined by multiplying a calculated velocity pressure by the drag coefficient of the structure.

Interparticle Potential and Drag Coefficient in Nematic Colloids

Physical Review Letters, 2006
Magneto-optic tweezers were used for measurements of liquid-crystal-mediated forces between spherical beads with tangential anchoring in thin nematic samples. Repulsive force, which results from the quadrupolar symmetry of defects around the immersed beads, decreases proportionally to 1/x6, with x being the bead separation.

On the drag coefficient of triangular profiles

Meccanica, 1988
Results of a laboratory study on the determination of the drag coefficient of triangular profiles simulating a train of sedimentary dunes are here presented. The study is carried out in a low speed wind tunnel by performing a direct measurement of the total drag force acting on one of the profiles and then subtracting the skin shear force to obtain 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 ...

Drag coefficients in rarefied flow [PDF]

The X1 expansion tube of the Centre for Hypersonics at the University of Queensland has developed and studied a test facility for hypervelocity rarefied flow. Dr. Macrossan has proposed the approximate theory of the drag of a blunt body in rarefied flow which is a modification of Whitfield’s theory (Macrossan, 2002b).

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.
