The viscous force per unit area "'? "', exerted by the flow on the surface on the sphere, is in the " z " direction everywhere.
22.
The fluid flows in microfluidic and nanofluidic devices are often stable and strongly damped by viscous forces ( with Reynolds numbers of order unity or smaller ).
23.
With a strong predominance of inertial forces over viscous forces, the largest scales of fluid motion are undamped there is not enough viscosity to dissipate their motions.
24.
When the two forces ( viscous force and the centrifugal force ) balance ( they are oppositely directed ), the particle moves with constant velocity called the terminal velocity.
25.
These regions are usually in the vicinity of the boundary of the fluid adjacent to solid surfaces where viscous forces are at work, such as in the boundary layer.
26.
By using the transient and viscous force equations for a cylindrical flow you can predict the transient boundary layer thickness by finding the Womersley Number ( N _ w ).
27.
It was previously believed that there was an intramuscular viscous force that increased proportionally to the velocity of muscle contraction that opposed the contractile force; this theory has since been disproved.
28.
The force acting on the particle is written as a sum of a viscous force proportional to the particle's velocity ( Stokes'law ), and a Gaussian probability distribution with correlation function
29.
Reynolds number ( Re ) is the measure of the relationships between inertial and viscous forces in flow ( ( animal's length x animal's velocity ) / kinematic viscosity of the fluid ).
30.
In the case of inertial instability such as Taylor Couette flow, the Taylor number is mathematically analogous to the Grashof number which characterizes the strength of buoyant forces relative to viscous forces in convection.
