The drag from the tilted matter dominates over the Lorentz force resulting in same sign flow for both $D^0$ and $\\overline{D^0}$, albeit of different magnitudes. Their average directed flow is about ten times larger than their difference. This charge splitting in the directed flow is a...
Measurements were made to assess the increase in drag on aquaculture cage netting due to biofouling. Drag force was obtained by towing net panels, perpendicular to the incident flow, in experiments conducted in a tow tank and in the field. The net panels were fabricated from netting stretched ...
We introduce force in dynamic brand logos as a cue to brand work and subsequent brand energy; constructs we develop and distinguish from brand engagement. We argue the phenomenon observed is due to a brand work-energy effect, whereby the depiction of a drag force (opposite direction to motion...
The friction force is the drag against sliding, appearing along the contacting surfaces. According to whether or not two bodies move relatively, the friction forces are classified into the static and the dynamic ones. They have the different physical origins [1]. Two pictures (or models) have ...
{DEP}}\)and can be correlated to the dielectric properties of microparticles including biological cells21,22,31,35,36. However, due to drag force phenomenon, the yield of LOC devices is extremely low at higher flow rates37. To circumvent this constraint, the\({F}_{\mathrm{DEP}}\)induced...
The integration of the force density on both separated vortex layers and on the back-flow region gives two instantaneous contributions to the total force. For the mean drag it is found that the back-flow contribution increases from almost 0 of the total drag at =50–20 of the total drag ...
It is found that in addition to the drag force determined by Stokes, the sphere experiences a force FL orthogonal to its direction of motion. This force is given by ${\bf F}_L = \pi a^3 ho \Omega imes {\bf V}[1 + O(R)]$ .Here a is the radius of the sphere, Ω is its...
A/ 2 corresponds to the dissi- pated power due to drag and v wind is the tailwind speed, which was zero in Beijing and equal to 0.9 m/s in Berlin. For C d =0.5, a typical value of the drag coefficient, 5,8 =1.2 kg/ m 3 for the air density, and a cross section of A...
Significantly stronger than the gravitational forces, the interparticle forces of Group C particles are hard to be overcome by the drag forces exerting on the particles by the fluidizing gas, making the individual particles cling together to form agglomerates [42]. As a result, the interparticle ...
As seen in §3.1.3, the drag force applied to a sphere moving in a viscous fluid at a speed of v is: F=6πμrv where μ is the coefficient of viscosity of the fluid and r the radius of the sphere. The ratio between the drag force F and the mass of the body, M, is: (3.16...
