The paper investigates the liquid polymer-bitumen binder in a pipe with sudden expansion. At small values of expansion parameter, formation high-viscosity zone occurs axial region, and effective viscosity decreases at periphery nearwall zones. destruction process structural bonds, which intensively proceeds near flow from supply pipe, leads to decrease viscosity. corner area reverse flows is ac...

Background: Alginate materials have been widely employed for biomedical applications ranging from wound healing to cancer treatment. However, how alginate materials affect the immune system is largely unknown. Objective: To explore the impact of alginate materials on immune system. Methods: The effect of three types of alginate materials, low viscosity, high viscosity and particulate alginate, ...

We study numerically the applicability of the effective-viscosity approach for simulating the effect of gravitational instability (GI) in disks of young stellar objects with different disk-to-star mass ratios ξ. We adopt two α-parameterizations for the effective viscosity based on Lin & Pringle (1990) and Kratter et al. (2008) and compare the resultant disk structure, disk and stellar masses, a...

Viscosity is an important property to known in energy engineering. Most lubricants are named after a ranking system that is directly related to how viscous that sample is. In addition to this, liquid fuels that are too viscous cannot achieve proper combustion in engines. In this report, a sample of baby oil was tested using Saybolt Universal viscometry to illustrate how increases in temperature...

Rheological characteristics of alumina (Al2O3) nanofluids (NFs) were found to exhibit an unexpected behavior. Two base-fluids viz, water and ethylene glycols (EG) with particles of average diameter of 11, 45 and 150 nm were examined. An anomalous reduction in viscosity compared to that of the base fluid was seen for EG based NFs. However, viscosity reduction was absent in water based NFs. The i...

The effects of fluid viscosity on the kinematics of a small swimmer at low Reynolds numbers are investigated in both experiments and in a simple model. The swimmer is the nematode Caenorhabditis elegans, which is an undulating roundworm approximately 1 mm long. Experiments show that the nematode maintains a highly periodic swimming behavior as the fluid viscosity is varied from 1.0 to 12 mPa s....

The aim of this study was to investigate how physico-chemical properties of two dietary fibres, guar gum and pectin, affected weight gain, adiposity, lipid metabolism, short-chain fatty acid (SCFA) profiles and the gut microbiota in male Wistar rats fed either low- or high-fat diets for three weeks. Both pectin and guar gum reduced weight gain, adiposity, liver fat and blood glucose levels in r...

Polymer flooding is now considered a technicallyand commercially-proven method for enhanced oil recovery (EOR). The viscosity of the injected polymer solution is the key property for successful polymer flooding. Given that the viscosity of a polymer solution has a non-linear relationship with various influential parameters (molecular weight, degree of hydrolysis, polymer concentration, cation c...

Experimental studies were conducted on an off-highway heavy duty diesel engine running on different viscosity grade engine oil, for determining the friction power in a firing engine by measuring the indicated mean effective pressure (IMEP) by in–cylinder pressure sensor and calculating the Indicated power and Brake power. It is known fact that hydrodynamic friction is related to the viscosity o...
