Traditionally water-ethylene glycol mixture based nanofluids are used in cold regions as a coolant in the car radiators. In the present study, the rheological properties of water-ethylene glycol based graphene oxide nanofluid are studied using Non-Equilibrium Molecular Dynamics (NEMD) method at different temperatures, volume concentrations, and shear rates. NEMD simulations are perfor...

Various scaling methods such as relative viscosity, Peclet and Reynolds scaling were used to find the best scaling law. Scaling and modeling of the flow curves of various model emulsions consist of Tragacanth Gum (TG) (0.5, 1 % wt), Oleic acid (5, 10% v/v) and WPI (2, 4 % wt) were investigated and the best models were selected. As these emulsions are non-Newtonian, they do not obey the usual...

in the present research work, influence of fleawort (plantago ovate l.) seed hydrocolloid at three concentration level (0.1, 0.15 and 0.2%) was investigated on physicochemical, textural and sensory characteristics of low fat yoghurt. the treated yoghurt samples were compared with a positive (3% fat) and negative (0.2%) control sample after 1, 7 and 15 days of storage. fleawort seed hydrocolloid...

The study provides information on the blood fluidity in healthy, juvenile sheep and rabbits during growth (n = 18), and shows also data from fetal rabbits and cats. In the fetal rabbit (n = 3) and cat (n = 2), whole blood viscosity (WBV; LS30, Contraves, Switzerland) and plasma viscosity (PV; OCR-D, Paar, Austria) was low (WBV (0.7 s(-1)): rabbit: 3.28/3.00/2.44; cat: 7.87/10.88; WBV (94 s(-1))...

mold powders in continuous casting of steel contain fluorine through mainly caf2 and occasionally naf andna3alf6. fluorine develops dangerous gases such as sif4 and hf at high temperatures. in this study, caf2 is partly replaced by substances such as na2co3, zno and fe2o3.sulfur free portland cement clinker containing gypsum was used as a new product base. these additions developed comparable v...

Research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. In particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthen...

Viscosity, a key property for glass processing, is a function of glass composition and temperature. Nuclear waste glasses must be formulated to obtain a desired viscosity at the melter processing temperature for each waste composition to be vitrified. Over the past decades, a large viscosity database has been accumulated at various laboratories in the US. The database, compiled at the Pacific N...

stabilizers have been used to improve the texture of ice cream for several decades. they added it to ice cream to control ice and lactose crystal growth during hardening and storage, to give body and stiffness during freezing for air incorporation and to impart smoothness in body and texture. nowadays, most of the industrial stabilizers are provided from abroad, so, extraction, determination of...

In matrix acidizing operations, the main goal is increasing permeability. For production engineers, it is desirable that acid could be injected into whole [M.N.1] [amehri.gh2] pay zone. Sometimes, this pay zone has a long height and various sub-layers which have different permeability values. To prevent acid from going completely into the most permeable sub-layer, one of the useful techniques i...
