A Numerical Study of Drop Motion in Poiseuille Flow
The cross-stream migration of a deformable drop in two-dimensional Poiseuille flow at finite Reynolds numbers is studied numerically. In the limit of a small Reynolds number (<1), the motion of the drop depends strongly on the ratio of the viscosity of the drop fluid to the viscosity of the suspending fluid. For a viscosity ratio 0.125, the drop moves toward the centre of the channe while for t...

متن کاملLateral Migration and Rotational Motion of Elliptic Particles in Planar Poiseuille Flow
Simulations of elliptic particulate suspensions in the planar Poiseuille ow are performed by using the lattice Boltzmann equation. E ects of the multi-particle interaction on the lateral migration and rotational motion of both neutrally and non-neutrally buoyant elliptic particles are investigated. Low and intermediate total particle volume fraction fa = 13%, 25%, and 40% are considered in this...
متن کاملMotion planning and trajectory tracking for three-dimensional Poiseuille flow
We present the first solution to a boundary motion planning problem for the Navier–Stokes equations, linearized around the parabolic equilibrium in a threedimensional channel flow. The pressure and skin friction at one wall are chosen as the reference outputs as they are the most readily measurable ‘wall-restricted’ quantities in experimental fluid dynamics and also because they play a special ...
متن کاملDirect Simulation of the Motion of Solid Particles in Couette and Poiseuille Flows of Viscoelastic Fluids
This paper reports the results of direct numerical simulation of the motion of a two-dimensional circular cylinder in Couette flow and in Poiseuille flow of an Oldroyd-B fluid. Both neutrally buoyant and nonneutrally buoyant cylinders are considered. The cylinder's motion and the mechanisms which cause the cylinders to migrate are studied. The stable equilibrium position of neutrally buoyant pa...
