This paper was aimed to address the modeling of effective thermal conductivity and viscosity of carbon structured nanofluids. Response surface methodology, D_optimal design (DOD) was employed to assess the main and interactive effects of temperature (T) and weight percentage (wt %) to model effective thermal conductivity and viscosity of multi wall and single wall carbon nanotube, CVD and RGO G...

In this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. The results showed that change in phase density ratio had no effect on phase inversion hold-up. It also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...

We have developed a finite element model of convection in a spherical, axisymmetric shell that we use to simulate upwelling thermal plumes in the mantle. The finite element method provides the flexibility to include realistic properties such as temperature-dependent viscosity, the focus of this paper. We used this model to investigate the effect of temperature-dependent viscosity on the structu...

Increases in the viscosity of blood and plasma predict clinical manifestations of atherothrombotic vascular disease. The clinical utility of viscosity measurements in cardiovascular risk factor analysis requires reference values established from a healthy disease-free population. A cohort of 126 (71 men, 55 women) healthy nonsmoking adults had fasting blood analysis after a 12-14-h fast. Viscos...

The effects of some synthetic sweeteners on the rheological and physical properties of guar gum in dilute solutions were investigated.Measurements include the determination of intrinsic viscosity and the particle size, surface weighted mean [D3, 2], volume weighted mean [D4,3] and specificsurface area ofguar gum andsyntheticsweeteners mixtures. T...

Viscosity is a fundamental physical parameter that influences diffusion in biological processes. The distribution of intracellular viscosity is highly heterogeneous, and it is challenging to obtain a full map of cellular viscosity with detailed organelle information. In this work, we report 1 as the first fluorescent viscosity probe which is able to quantitatively map cellular viscosity with de...

The state of melt viscosity in injection process is significantly influenced by the setting parameters due to that the shear rate of injection process is higher than other processes. How to determine plastic melt viscosity during injection process is important to understand the influence of setting parameters on the melt viscosity. An apparatus named as pressure sensor bushing (PSB) module that...

Small amounts of potassium oxalate probably have no effect on the viscosity of the blood and changes hitherto ascribed to it can be attributed either to variation in carbon dioxide content or to sedimentation of the red blood cells. The viscosity of blood when exposed to the air increases rapidly. This change accompanies a loss of carbon dioxide and can be prevented by stoppering the container ...

We study the behavior of spectral viscosity approximations to nonlinear scalar conservation laws. We show how the spectral viscosity method compromises between the total-variation bounded viscosity approximations { which are restricted to rst-order accuracy, and the spectrally accurate { yet unstable, Fourier method. In particular, we prove that the spectral viscosity method is L 1-stable and h...
