Lima In this article, we study the relation between viscosity and temperature of several biodiesel types (soybean, sunflower...

... thermal conductivity enhancement of 16 % for Al-5 wt. %Zn and 13 % for Al-5 wt. %Si dispersed nanofluids are observed at 0.1 vol. % of nanoparticle concentrations. Rheological studies of nanofluids show interesting findings as the viscosity of both types of nanofluids are observed to exhibit values lower...

... content, and determination of in-service oil viscosity. In each case, quite different technological solutions have been adopted. Where applicable, alignment and overlap with existing ASTM methods and practices will be reviewed and future directions indicated. Recent improvements in the sensitivity...

... such as pour point, flash point, lubricity of diesel-like fuel in high frequency reciprocating rig, high-temperature/high-shear viscosity, and viscosities as function of temperature, extreme pressure behavior, oxidation resistance as well as its toxicity and bio-degradability. These properties are compared...

... of the cone and a diameter of 50 cm, and between a diameter of 50 cm and the final diameter. In addition, the rapid penetration test was used to compare dynamic and static segregation characteristics. References Khayat , K. H. , “ Viscosity-Enhancing Admixtures for Cement-Based Materials...

...” geometry. From this family of materials, four were chosen for comparison to three commercially available benchmark dispersants in several typical pesticide suspension concentrates. The criteria used to compare the new to the old dispersants were: ability to reduce suspension viscosity, zeta potential...

...DJ Moonay, PhD A new algorithm written in commercially available software controls programmable viscometers and rheometers so that multiple decades of apparent viscosity data may be acquired. This work is new and important because previous methods involved either: (1) very simple instrumentation...

...F Nihal Tüzün In this study, three different HTPB (hydroxyl terminated polybutadiene) based composite propellants were developed by varying the aluminium (Al) content 16, 18, and 20 %; and the effect of aluminium content variation on burning rate, P-K relationship, viscosity, heat of explosion...
