In 1861, Maxwell derived two of his equations of electromagnetism by modelling a magnetic line of force as a ‘molecular vortex’ in a fluid-like medium. Later, in 1980, Berry and colleagues conducted experiments on a ‘phase vortex’, a wave geometry in a fluid which is analogous to a magnetic line of force and also exhibits behaviour corresponding to the quantisation of magnetic flux. Here we uni...

Kinetics of magnetic flux in the thin mesoscopic ring biased by an external magnetic flux exhibits the ratchet-like behavior. The 'flux velocity', i.e. the averaged time derivative of magnetic flux produced by the ring, is a candidate for a novel characteristics of mesoscopic rings. Its global properties reflect the possibility of accommodating persistent currents in the ring. 1 Mesoscopic ring...

In the current study, the kinetics of asphaltene particle flocculation is investigated under a shear flow through numerical simulation. The discrete element method (DEM) is coupled with computational fluid dynamics (CFD) to model the agglomeration and fragmentation processes. In addition, a coalescence model is proposed to consider the attachment of colliding particles. The changes in mean asph...

the primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. in previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. in the present study, however, we present a novel model that accommodates for...

Using an elegant transform domain iterative operator approach exhaustive fluid vacation models with strictly negative fluid rate during service has been analyzed, recently. Unfortunately, the potential presence of positive fluid rate during service (when the fluid input rate is larger than the fluid service rate) inhibits the use of all previously applied methodologies and makes the extension o...
