Computer simulation of ordering and dynamics in liquid crystals in the bulk and close to the surface
… a virtual exper- iment resembling the classical falling sphere experiment. The falling sphere is replaced by an hydrogenated silicon nanoparticle of spherical shape suspended in 5CB, and gravity effects are replaced by a constant force applied to the nanoparticle in a selected direction. Once the …

Transient state analysis of separated flow around a sphere
… was obtained for incompressible flow around a sphere accelerating from zero initial velocity to its terminal free falling velocity. By assuming rotational symmetry around the axis in the falling direction, the Navier Stokes equation and the continuity equation were simplified in terms of …

An experimental and theoretical study of the flow about spheres and discs rotating slowly in viscoelastic fluids
An analysis of the flow about a sphere rotating slowly in a Rivlin-Ericksen fluid contained in a stationary outer concentric sphere is presented. An application of the conformal mapping technique is proposed. The technique is used to obtain the radial and axial velocity components for the flow …

The transient motion of a solid sphere between parallel walls
… of the velocity field in a fluid around a solid sphere undergoing transient motion parallel to, and midway between, two plane walls. Particle Image Velocimetry (PIV) was used to measure the velocity at many discrete locations in a plane that was perpendicular to the walls and included the centre …

Mantle-Melting at High Pressure: Experimental Constraints on Magma Ocean Differentiation
… was investigated at high pressure using in-situ falling sphere viscometry. Experiments were performed between 2.5 and 13 GPa at temperatures between 2043 to 2523 K. Measured viscosities range from 0.018 (±0.003) to 0.13 (±0.01) Pa s. Up to 9 GPa the data indicate an isothermal increase in …
