The drag force exerted on the dust by a moving fluid due to the viscous surface shear stress and pressure distribution around the dust particles depends mainly on the Reynolds number, i.e. property of the fluid (kinematic viscosity), its mean velocity and characteristic length of the geometry.
The problem of three-dimensional bubble injection from an orifice into quiescent water using various volumetric flow rates is used to assess the numerical model under capillary dominant conditions and conditions where the interplay between inertial, viscous, surface tension, and buoyancy forces cause a complex interface deformation.
Swarming motility is a flagellum-dependent, coordinated, multicellular behavior promoting rapid bacterial colony migration and expansion on more viscous surface, such as the epithelial lining layer that P. aeruginosa encounters after inhalation into the alveolar space.
An important phenotype regulated by AHL QS in P. aeruginosa is the swarming motility, which is a community phenomenon involving the fast movement of a bacterial population on a semi-solid, viscous surface [ 6].
A new surface-capturing method is developed for numerically simulating viscous free surface flows in partially filled containers.
In a microspace, viscous force, surface tension, conduction heat transfer, and molecular diffusion become dominant.
A finite element method is presented for the numerical simulation of time-dependent incompressible viscous free surface flows.
Processes such as Knudsen diffusion, viscous flow, surface diffusion and heat effects are accounted for in the model.
Accounting for inner viscous transport, surface tension and placing no restrictions on either the motion or the shape of the jet's center-line, it generalizes the previously developed string models for straight [9 11] and curved [12 14] center-lines.
