Particle dispersion in two-dimensional peristaltic flow
Abstract Particle dispersion in a two-dimensional peristaltic flow with zero pressure rise is investigated. It is found that, depending on the degree of occlusion of the peristalsis, particle motion can be forward or retrograde. Dispersion of a group of particles is quantified using the mean particle position and the variance around this. The degree of occlusion of the wave can be used to promo...
متن کاملStreamline topologies of two-dimensional peristaltic flow and their bifurcations
Streamline patterns and their local and global bifurcations in a two-dimensional peristaltic flow for an incompressible Newtonian fluid have been investigated. An analytical solution for the stream-function is found under a long-wavelength and low-Reynolds number approximation. The problem is solved in a moving coordinate system where a system of nonlinear autonomous differential equations can ...

15 صفحه اولParticle motion in unsteady two-dimensional peristaltic flow with application to the ureter.
Particle motion in an unsteady peristaltic fluid flow is analyzed. The fluid is incompressible and Newtonian in a two-dimensional planar geometry. A perturbation method based on a small ratio of wave height to wavelength is used to obtain a closed-form solution for the fluid velocity field. This analytical solution is used in conjunction with an equation of motion for a small rigid sphere in no...
متن کاملAnalysis and Visualization of the Two-Dimensional Blood Flow Velocity Field from Videos
We estimate the velocity field of the blood flow in a human face from videos. Our approach first performs spatial preprocessing to improve the signal-to-noise ratio (SNR) and the computational efficiency. The discrete Fourier transform (DFT) and a temporal band-pass filter are then applied to extract the frequency corresponding to the subjects heart rate. We propose multiple kernel based k-NN c...
