In this paper, we numerically study the dynamics of (1) a Newtonian liquid-filled capsule in a viscoelastic matrix and that of (2) a viscoelastic capsule in a Newtonian matrix in a linear shear flow using a front-tracking method. The numerical results for case (1) indicate that the polymeric fluid reduces the capsule deformation and aligns the deformed capsule with the flow direction. It also n...

This summer project reproduces the foam experiment from previous summer but with oilwater emulsions. Increasing the viscosity of oil changes the droplets from soft to hard as well as the behavior from Newtonian liquid to granular matter. The expected outcome is Bachelor’s or Master’s Thesis or similar report depending on applicant’s background. The applicant is expected to have keen interest in...

The vortex ow which follows intense sound propagating in a bubbly liquid, is considered. The reasons for acoustic streaming are both nonlinearity and dispersion. That makes streaming especial as compared with that in a Newtonian uid. Conclusions concern the vortex ow induced in a half-space by initially harmonic or impulse Gaussian beam. The vortex ow recalls a turbulent ow with increasing in t...

A numerical study of hemodynamic parameters of pulsatile blood flow is presented in a stenotic artery with A numerical study of hemodynamic parameters of pulsatile blood flow is presented in a stenotic artery with non-Newtonian models using ADINA. Blood flow was considered laminar, and the arterial wall was considered rigid. Studied stenosis severities were 30, 50, and 70% of the cross-section...

In the current literature, information can mainly be found about free and hindered settling of isometric particles in Newtonian non-Newtonian fluids. These conclusions cannot used to describe sedimentation non-isometric particle For this reason, we have carried out systematic experiments calculated correlation velocity a cloud high-viscosity pseudoplastic liquid. The were performed transparent ...
