Hydrodynamic Determination of the Kinematic Viscosity of Waste Brines. [PDF]

open access: yesACS Omega, 2019
Wastewater from a potash mine in the central region of Catalonia is transported by means of a collector that runs more than 100 km, spilling into the sea on the Catalan central coast. To analyze the hydraulics of this infrastructure, the values of the basic parameters that condition the flow, such as the absolute roughness of poly(vinyl chloride) (PVC)

Undulatory swimming in shear-thinning fluids: Experiments with C. elegans [PDF]

open access: yes, 2014
The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of shear-thinning viscosity on the swimming behaviour of an undulatory swimmer ...

Water model study on critical slag entrapment behavior based on PIV technology

open access: yes工程科学学报, 2016
The slag entrapment process and the flow field of a specific ladle at critical flow rate are investigated based on particle image velocimetry(PIV) technology,and the change of fluid velocity at the region where slag is entrapped into steel during the ...

The structure of shock waves as a test of Brenner's modifications to the Navier-Stokes equations [PDF]

open access: yes, 2006
Brenner (Physica A, vol. 349, 2005a, b, pp. 11, 60) has recently proposed modifications to the Navier-Stokes equations that are based on theoretical arguments but supported only by experiments having a fairly limited range.

Evaluation Properties and PNA Analysis for Different Types of Lubricants Oils

open access: yesIraqi Journal of Chemical and Petroleum Engineering, 2019
A study of characteristics of the lubricant oils and the physical properties is essential to know the quality of lubricant oils. The parameters that lead to classify oils have been studied in this research. Three types of multi-grades lubricant oils were
