Periodic structures in a colloidal crystal submitted to an oscillatory flow

چکیده
2014 A colloidal crystal retained in a cylindrical tube and submitted to an oscillatory flow exhibits under certain conditions a spatially periodic pattern. Optical observations of the colored flecks show the existence of a continuous modulation of the orientation of the crystallites at the tube surface. It is due to the presence of a transverse component in the velocity field. We also present new experimental results concerning the wavelength of this pattern as a function of frequency and motion amplitude. J. Phys.

Fluidic Oscillators’ Applications, Structures and Mechanisms – A Review
Enhancement of heat and mass transfer and decrease of energy dissipation are great necessities of the evolution of fluid flow devices. Utilizing oscillatory or pulsatile fluid flow for periodic disturbing of velocity and thermal boundary layers is one of the methods with exciting results. Passive methods of generating oscillatory flow are preferred to active methods because of simplicity, no ne...

متن کاملThermal Field Around a Circular Cylinder with Periodic Vortex Shedding
A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...
متن کاملUnsteady free convection oscillatory couette flow through a variable porous medium with concentration profile
In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...
متن کاملTime-periodic Electroosmotic Flow of Non-newtonian Fluids in Microchannels
The alternating current electroosmotic flow of a non-Newtonian power-law fluid is studied in a circular microchannel. A numerical method is employed to solve the non-linear Poisson-Boltzmann and the momentum equations. The main parameters which affect the flow field are the flow behavior index, the dimensionless zeta potential and the dimensionless frequency. At very low dimensionless frequenci...
