fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...

We present a detailed study of a salt-free cationic/anionic (catanionic) surfactant system where a strongly alkaline cationic surfactant (tetradecyltrimethylammonium hydroxide, TTAOH) was mixed with a single-chain fluorocarbon acid (nonadecafluorodecanoic acid, NFDA) and a hyperbranched hydrocarbon acid [di-(2-ethylhexyl)phosphoric acid, DEHPA] in water. Typically the concentration of TTAOH is ...

Nanofluids are new generation heat transfer fluids and have opened a new horizon in the areas of heat transfer applications. Nanofluids are prepared by dispersing nano-sized metallic particles in conventional fluids of heat transfer. Heat transfer performance of nanofluid depends primarily on its thermo physical properties like viscosity, thermal conductivity, specific heat and density. Viscosi...

Graphene oxide (GO) liquid crystals (LCs) are macroscopically ordered GO flakes dispersed in water or polar organic solvents. Since the first report in 2011, GO LCs have attracted considerable attention for their basic properties and potential device applications. In this review, we summarize recent developments and present a comprehensive understanding of GO LCs via many aspects ranging from t...

The aim of this study was to produce the ice cream with potential antidiabetic effects by addition of pistachio peel extract (PPE) (0, 10, 20 and 30% on dry matter basis). The properties of produced ice creams such as physicochemical, rheological, antioxidant, antidiabetic and sensory properties were evaluated. The results indicated that ice creams containing 20 and 30% of PPE provided desired ...

We have studied the rheological property evolution and hydration behavior of white and ordinary portland cement (type I) pastes and concentrated cement–polyelectrolyte suspensions. Cement composition had a marked effect on the elastic property evolution (G (t)) and hydration behavior of these suspensions in the presence of poly(acrylic acid)/poly(ethylene oxide) copolymer (PAA/PEO), even though...

Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...

Similar to the asphalt mixture, polyurethane (PU) mixture’s performance and characteristics are dependent on many variables. In this study, six variables, including aggregate gradation (limestone basalt), type, PU content, curing condition, several parameter analyzing methods were chosen determine effect of variables dynamic property, rheological rutting resistance mixture. The limestone exhibi...

The Al2O3–CaO–SiO2 ternary is a basic oxide system relevant for the Pedersen alumina production process and aluminothermic silicon with low environmental impact using secondary aluminium silica raw materials. Rheological property one of most important properties above applications. A phenomenological viscosity model, inspired by Calphad technique, has been proposed description rheological cover...
