A refined model is presented which numerically resolves the fluid flow within a fracture inside saturated poroelastic material. At discontinuity, mass balance of solved using velocity profile fracture, with being determined from momentum in integration points at discontinuity. The resolution and discontinuity coupled to surrounding material two-scale approach. resulting monolithic scheme allows...

Silicone fluids belong to the group of pseudoplastic non-Newtonian with complex rheological characteristics. They are considered in basic and applied researches a wide range industrial applications due their favorable physical thermal properties. One specific field automotive industry is working fluid viscous torsional vibration dampers. For numerical studies design development phase this dampi...

The aim of this study is to investigate the effects of non-Newtonian blood rheology models on the wall shear stress (WSS) distribution in a cohort of patients-specific coronary arteries. Twenty patients with diseased left anterior descending (LAD) coronary arteries (with varying degrees of stenosis severity from mild to severe) who underwent angiography and in-vivo pressure measurements were se...

The motion of a long gas bubble in confined capillary tube is ubiquitous wide range engineering and biological applications. While the understanding deposited thin viscous film near wall Newtonian fluids well developed, deposition dynamics commonly encountered non-Newtonian remains much less studied. Here, we investigate moving shear-thinning with systematic experiments, varying zero-shear-rate...

Nanofluids are considered as an effective way to enhance the thermal conductivity of heat transfer fluids. Additionally, involvement micro-organisms makes liquid more stable, which is important in nanotechnology, bio-nano cooling systems, and bio-microsystems. Therefore, current investigation focused on examination thermodynamic mass a Carreau–Yasuda magnetic bionanomaterial with gyrotactic mic...

One of the main causes death is atherosclerosis so, in this work, two models stenosed arteries have been executed numerically to assess hemodynamic effects caused by flow disruptions. Using Computational Fluid Dynamics (CFD) provide information public, particularly surgeons, and assist them reducing risk stenosis. Star-CCM+ software was used perform CFD techniques such as steady, turbulent, non...

A spectral element—Fourier method (SEM) for Direct Numerical Simulation (DNS) of the turbulent flow of non-Newtonian fluids is described and the particular requirements for non-Newtonian rheology are discussed. The method is implemented in parallel using the MPI message passing kernel, and execution times scale somewhat less than linearly with the number of CPUs, however this is more than compe...
