Aspects of Rheological Behavior of Rapeseed Oil
(Universitatea ”Dunărea de Jos” din Galați, 2009)This paper presents a study of dynamic viscosity variation with shear rate for rapeseed oils obtained from different stages of processing and the hydraulic oil grade H32. For each of the 6 types of oils studied was determined ... -
Effect of Oxidation on Spectrophotometric and Rheological Parameters of Corn Oil
(Universitatea "Dunărea de Jos" din Galați, 2013)The aim of this study is the viscosity’s evolution depending on the temperature and the shear rate and the analysis of the transmittance spectra of the oxidized corn oil. Corn oil was oxidized of the temperatures of ... -
Improvement of Steel Sheet Corrosion Resistance by Thermic Coverage Method with Zinc-Aluminium Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)The paper presents the main physico-chemical characteristics (viscosity and superficial tension of zinc-aluminium liquid alloy in view of carry out protected layers on steel sheet with very good properties by thermal ... -
On Viscosity Variation with Temperature of Rapeseed Oil After Different Processing Stages
(Universitatea ”Dunărea de Jos” din Galați, 2009)In recent years, vegetal oils are carefully studied as they may constitute a category of basic raw materials for obtaining organic biodegradable lubricants. Rapeseed oil is seen as an alternative of mineral and synthetic ... -
Properties of Slags in the System CaO-MgO-Al2O3-SiO2, Important in Deoxidization and Desulphurization of Low Carbon Aluminium Killed Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2012)Properties of refing slags belonging to the system CaO-MgO-Al2O3-SiO2 are important in simultaneous or succesive refinig treatment processes in the ladle and other refing metalurgical reactors. The efficiency of treatments ... -
A Review on the Thermophysical Properties of Water-Based Nanofluids and their Hybrids
(Universitatea "Dunărea de Jos" din Galați, 2016)A nanofluid is a solid–liquid mixture which consists of nanoparticles and a base liquid. Nanoparticles are basically metal (Cu, Ni, Al, etc.), oxides (Al2O3, TiO2, CuO, SiO2, Fe2O3, Fe3O4, BaTiO3, etc.) and some other ... -
Rheological and Tribological Study on Soybean Oil
(Universitatea "Dunărea de Jos" din Galați, 2014)In this work the temperature and share rate influence on soybean oil viscosity was studied. Moreover, a statistical analysis of the experimental data obtained by a tribological study of this oil was carried out. ... -
Studies on the Effects of Olive Oil Oxidation
(Universitatea "Dunarea de Jos" din Galați, 2013)The aim of this study is the viscosity’s evolution depending on the temperature and the shear rate and the analysis of the transmittance spectra of the oxidized olive oil. Oxidation of olive oil is a process that leads ... -
Study on the Rheology of Corn Oil Subjected to Forced Oxidation
(Universitatea "Dunărea de Jos" din Galaţi, 2014)This paper reflects a study on the rheology of corn oil in unoxidized state, subjected to forced oxidation treatment. Using the Rheotest2 system, the variation of dynamic viscosity with temperature and shear rate, using ... -
Values of the Solutal Marangoni Number in Very Dilute Fe-C-O Solutions at 1873K
(Universitatea "Dunărea de Jos" din Galați, 2007)Low carbon, aluminum killed steels are well represented by the adequate part of the Fe-C-O system, where are available useful experimental data, regarding the surface tension and viscosity. The reference dynamic ... -
Viscosity of Amorphous Molecular Substances
(Universitatea ”Dunărea de Jos” din Galați, 2008)Because the great majority of flow units in a liquid behave instantaneously in a solid-like manner, rheological properties of molecular liquids subjected to high pressures may be measured by using corresponding molecular ...
