In this paper we assume determination of pseudo-viscosity coefficients of visco-elastic non-Newtonian fluid flow directly near the cooperating micro-bearing surface. We show the constitutive stress-strain dependencies of nonNewtonian visco-elastic media with regard to the content of addition of nano-particles. The greater content of nano-particles and influences of superficial layer of cooperat...

The purpose of this research is to scrutinize thermally charged heated bi-phase nanofluid flow in elongated parallel slippery walls governed by an external pressure gradient. couple stress subject suspension with nano-sized metallic particles. interaction effects a transverse magnetic field have been taken into account. lubrication at the are considered avoid roughness walls. Governing nonlinea...

The public is increasingly exposed to various engineered nanomaterials because of their mass production and wide application. Even when the biological effects of nanomaterials have been assessed, the underlying mechanisms of action in vivo are poorly understood. The present study was designed to seek a simple, effective, and oxidative stress-based biomarker system used for screening toxicity of...

Couple stresses because of magnetic particles additives on the lubrication performance a journal bearing system was embraced and scrutinized in current examinations theoretically. The governing equations Reynolds (pressure field), energy (temperature heat conduction field through solids) are coupled solved instantaneously term temperature viscosity. After these set equation pressure is obtained...

Regional distance seismic moment tensor determinations and broadband waveforms of moment magnitude 4.6 to 4.9 earthquakes from a November 1997 Long Valley Caldera swarm, during an inflation episode, display evidence of anomalous seismic radiation characterized by non-double couple (NDC) moment tensors with significant volumetric components. Observed coseismic dilation suggests that hydrothermal...

rheological characteristics of al2o3, cuo and tio2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. constitutive relations for non-newtonian fluid were discussedbased on the power-law model. measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. results indicated that the nanofluid viscosity decreasedby increasing the concentrat...

The present study investigates the peristaltic flow of couple stress fluid in a non-uniform rectangular duct with compliant walls. Mathematical modeling is based upon the laws of mass and linear momentum. Analytic solutions are carried out by the eigen function expansion method under long-wavelength and low-Reynolds number approximations. The features of the flow characteristics are analyzed by...

We present in this paper a review of some recent work dedicated to the numerical interfacial coupling of fluid models. One main motivation of the whole work is to provide some meaningful methods and tools in order to compute unsteady patterns, while using distinct existing CFD codes in the nuclear industry. Thus, the main objective is to derive suitable boundary conditions for both codes to be ...

The radiation and thermal diffusion effects on mixed convection flow of couple stress fluid through a channel are investigated. The governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations. The resulting equations are then solved using the Spectral Quasi-linearization Method (QLM). The results, which ar...
