Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often ...

Particle Image Velocimetry (PIV) is a laser‐based optical measurement technique that yields instantaneous, two- or three-dimensional velocity fields by tracking the displacement of seeding particles ...

Researchers discovered a trick for dragging an object in a fluid with minimal effort, suggesting an optimal strategy for nanorobots. What a drag. Laser-based optical tweezers (green) were used to drag ...

Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless ...

WHETHER it's the mechanics of a supernova, the ignition of an inertial confinement fusion (ICF) capsule, or the detonation of a nuclear weapon, simulating the motion of fluids is anything but simple.

What is the Stokes-Einstein Equation? The Stokes-Einstein equation is a fundamental relation in physics that describes the diffusion of spherical particles through a fluid with low Reynolds number. It ...
