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 ...
The drag force is shown to be generally not collinear with the velocity of the impurity. This unusual behavior is a consequence of condensation into a finite-momentum state due to the spin-orbit coupling.关键词: Condensed Matter - Quantum Gases ...
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 ...
Consequently, both the drag force in longitudinal direction and the lift force in lateral direction change accordingly. Time-dependent magnitudes of these two component forces set the stage for calculating transient resultant force. By contrast, many studies of conventional Savonius wind rotors calculate...
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...
Since the potential is non-diverging, there is no gas removal due to accretion. When R-s is larger than the Bondi radius R-B, the perturbation is linear at every point and the drag force is well fitted by the time-dependent Ostriker's formula with r(min) = 2.25R(s), where r(min...
The energy was transferred through the biofllm causing the underlying microcolonies to oscillate. The measured pressure drop was partially attributed to the loss of energy due to these flow induced vibrations and oscillations. 展开 关键词: Biofilm drag flow induced vibrations hydrodynamics pressure ...
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 ...
