Journal ArticleDOI
Viscosity, Interfacial Tension, Self-Diffusion Coefficient, Density, and Refractive Index of the Ionic Liquid 1-Ethyl-3-methylimidazolium Tetracyanoborate as a Function of Temperature at Atmospheric Pressure
Thomas M. Koller,Michael H. Rausch,Peter S. Schulz,Markus E. M. Berger,Peter Wasserscheid,Ioannis G. Economou,Alfred Leipertz,Andreas P. Fröba +7 more
TL;DR: In this article, surface light scattering (SLS) was used to estimate the interfacial tension of the ionic liquid (IL) in the range from (283.15 to 313.15) K with a vibrating U-tube densimeter.
Journal ArticleDOI
Liquid Viscosity and Surface Tension of n-Dodecane, n-Octacosane, Their Mixtures, and a Wax between 323 and 573 K by Surface Light Scattering
Thomas M. Koller,Tobias Klein,Cédric Giraudet,Jiaqi Chen,Ahmad Kalantar,Gerard P. van der Laan,Michael H. Rausch,Andreas P. Fröba +7 more
TL;DR: In this article, the surface light scattering (SLS) method was used to obtain the surface tension and viscosity of n-alkane-based model systems at temperatures up to 573 K.
Journal ArticleDOI
Effective thermal conductivity of nanofluids – A new model taking into consideration Brownian motion
TL;DR: In this article, a new analytical model for the effective thermal conductivity of liquids containing dispersed spherical and non-spherical nanometer particles was developed, which allows for the prediction of the thermal conductivities of nanofluids as a function of volume fraction, diameter, and shape of the nanoparticles as well as temperature.
Journal ArticleDOI
Liquid Viscosity and Surface Tension of n-Hexane, n-Octane, n-Decane, and n-Hexadecane up to 573 K by Surface Light Scattering (SLS).
Tobias Klein,Shaomin Yan,Shaomin Yan,Junwei Cui,Junwei Cui,Joseph W. Magee,Kenneth Kroenlein,Michael H. Rausch,Thomas M. Koller,Andreas P. Fröba +9 more
TL;DR: Empirical models for the liquid viscosity and surface tension of n-alkanes were developed as a function of temperature and carbon number covering values between 6 and 28 and agreement between these models and reference correlations for further selected n-alksanes which were not included in the development procedure was found.
Journal ArticleDOI
Measurement and Prediction of the Thermal Conductivity of Tricyanomethanide- and Tetracyanoborate-Based Imidazolium Ionic Liquids
Thomas M. Koller,Stefan R. Schmid,Swetlana J. Sachnov,Michael H. Rausch,Peter Wasserscheid,Andreas P. Fröba +5 more
TL;DR: In this article, the thermal conductivity of ten ionic liquids (ILs) based on the anions were measured by a steady-state guarded parallel-plate instrument in the temperature range between (283.15 and 353.15) K at atmospheric pressure with a total uncertainty of 5% with a standard deviation of less than 7%.
