WebJan 1, 2024 · These two drag regimes are briefly described below. A linear formulation of drag was first introduced as the Guldberg-Mohn approximation of virtual internal friction in 1876 (Neumann, 1968). Now known as Rayleigh drag, the approximation describes drag within a fluid that is proportional and opposite to the fluid’s velocity.

Webinduced drag.6 When a standing ultrasound wave is established in a microchannel containing a microparticle suspension, the parti-cles are subject to two acoustic forces: the acoustic radiation force from the scattering of sound waves on the particles, and the Stokes drag force from the induced acoustic streaming flow. The The force of viscosity on a small sphere moving through a viscous fluid is given by: where: • Fd is the frictional force – known as Stokes' drag – acting on the interface between the fluid and the particle • μ is the dynamic viscosity (some authors use the symbol η) WebRayleigh damping does afford certain mathematical conveniences and is widely used to model internal structural damping. ... For subsea lines the structural damping is usually negligible in comparison with the damping due to hydrodynamic drag, and so Rayleigh damping can usually be ignored for analysis of subsea lines. great outdoor photos
