fluid particle

Fluid particles are subject only to pressure and their own weight.

It is a measure of how hard the fluid particles are pushing their neighbours, on average.

Let and be two neighboring fluid particles, separated by at time t.

In other words, which quantities are invariant following fluid particles?

Applications to fluid particle path flows will also be discussed.

However, this appearance is often an illusion and the fluid particles are moving in closed paths.

The suffix indicates that we are following the motion of a fluid particle.

Consider a fluid particle that is displaced upwards, say, from its equilibrium position.

Dynamic pressure is the kinetic energy per unit volume of a fluid particle.

Recent work has for example employed topological methods to characterize the stretching of fluid particles.

Pathlines are the trajectories that individual fluid particles follow.

It is only appreciable if there are rotational degrees of freedom for the fluid particles.

While the surface elevation shows a propagating wave, the fluid particles are in an orbital motion.

So while the wave propagates, the fluid particles just orbit (oscillate) around their average position.

A flow promotes mixing by separating neighboring fluid particles.

A rational approach to determining an appropriate number of fluid particles that would generate the required computational precision is presented.

It describes the rate of change of vorticity of the fluid particle.

These quantum energy states of the fluid particles are found using their respective quantum Hamiltonian.

A fluid particle with positive v is being carried by the turbulence in the positive y-direction.

Fluid particles are unable to cross the boundaries of the islands (except by slow diffusion), resulting in segregation.

The fluid particles also have potential energy, which is associated with the fluid elevation above an arbitrary datum.

Fluid particles can interact with other principal particles.

In reality, these long-range effects are suppressed by the flow of the fluid particles in response to electric fields.

HPP model is a two-dimensional model of fluid particle interactions.

In chaotic advection, a fluid particle travels within a large region, and encounters other particles that were initially far from it.
