The morpholinium cation based ionic liquids are designed to evaluate the thermophysical, chemical reactivity, and biological activity. To estimate and design the bioactive ILs, propionate and trihalopropanoate were considered under theoretical study by Density Functional Theory (DFT). To make effect of halogens atom on anion, propionate, trifluro propionate, trichloro propionate, and tribromo p...

In support for the ISO Mission it has been necessary to establish a set of asteroids as photometric standards for the photometric calibration of the instruments (M uller & Lagerros 1998). The new standards are described as rotating ellipsoids. Illumination geometry, heat transfer due to non-zero thermal inertia and surface structure/porosity are taken into account. The characteristic properties...

This report presents the systematic study on the solubilities of 1-alkyl-3-methylimidazolium hexafluorophosphate [e, or bmim][PF6], 1-alkyl-3-methylimidazolium methylsulfate [almim][CH3SO4], 1-hexyloxymethyl-3-methylimidazolium ionic liquids (ILs) [C6H13OCH2mim][BF4], or [C6H13OCH2mim][(CF3SO2)2N] in aliphatic hydrocarbons (heptane, octane), cyclohydrocarbons (cyclopentane, cyclohexane) and aro...

Data on thermophysical properties are essential for modeling and evaluation of food processing operations involving heat transfer when safety, quality and energy cost are considered. Thermophysical properties of various meat and poultry emulsions were evaluated at 4 temperatures (20, 40, 60 and 80C). Thermal conductivities (0.26 W/mK to 0.48 W/mK) increased linearly with the temperature from 20...

Thermophysical properties of phase change materials (PCM) are of utmost importance in latent heat thermal energy storage (LHTES) applications. Therefore, an experimental study is conducted in order to determine thermophysical properties of five technical grade paraffin waxes produced by major Croatian oil company, INA d.d. Rijeka. The temperatures and enthalpies of melting and solidification (l...

Molecular simulation is a powerful tool for understanding and predicting thermophysical properties in systems both at equilibrium and away from equilibrium and composed of molecules ranging in complexity from spherically symmetric monatomic molecules to polymers. In recent years, our research group has applied molecular simulation to the study of supercritical aqueous solutions with the goal of...

In this paper, mixed convection of Al2O3-EG-Water nanofluid in a square lid-driven enclosure is investigated numerically. The focus of this study is on the effects of variable thermophysical properties of the nanofluid on the heat transfer characteristics. The top moving and the bottom stationary horizontal walls are insulated, while the vertical walls are kept at different constant temperature...
