Multiplex Particle Focusing via Hydrodynamic Force in Viscoelastic Fluids
We introduce a multiplex particle focusing phenomenon that arises from the hydrodynamic interaction between the viscoelastic force and the Dean drag force in a microfluidic device. In a confined microchannel, the first normal stress difference of viscoelastic fluids results in a lateral migration of suspended particles. Such a viscoelastic force was harnessed to focus different sized particles ...
متن کاملFluid-Structure Interaction Using the Particle Finite Element Method
In the present work a new approach to solve fluid-structure interaction problems is described. Both, the equations of motion for fluids and for solids have been approximated using a material (lagrangian) formulation. To approximate the partial differential equations representing the fluid motion, the shape functions introduced by the Meshless Finite Element Method (MFEM) have been used. Thus, t...
متن کاملParticle-wall interaction in a viscoelastic fluid
In this work, particle-wall interaction in viscoelastic fluids is experimentally studied. The effect of Stokes number, Weissenberg number and surface roughness on the rebound velocity of a colliding spherical particle on a wall is considered. Different steel spherical particles are released in viscoelastic solutions of different high-molecular-weight polymers in water with different concentrati...
متن کاملDiffusive behavior of a thin particle layer in fluid by hydrodynamic interaction.
The hydrodynamic effect on a thin particle layer, which moves relative to fluid by an external force, is investigated theoretically and numerically. Because of the presence of layer ends, the arrangement of particles in the layer is anisotropic and the drag force acting on them varies according to the position. The resulting relative motion of particles brings about the spreading of the layer. ...
متن کاملParticle-Based Mesoscale Hydrodynamic Techniques
– Dissipative particle dynamics (DPD) and multi-particle collision (MPC) dynamics are powerful tools to study mesoscale hydrodynamic phenomena accompanied by thermal fluctuations. To understand the advantages of these types of mesoscale simulation techniques in more detail, we propose new two methods, which are intermediate between DPD and MPC — DPD with a multibody thermostat (DPD-MT), and MPC...
