Viscosity of normal-hexadecane

The calculation of viscosity of liquid n-decane and n-hexadecane by the Green-Kubo method

This short commentary presents the result of long molecular dynamics simulation calculations of the shear viscosity of liquid n-decane and n-hexadecane using the Green± Kubo integration method. The relaxation time of the stress± stress correlation function is compared with those of rotation and di€ usion. The rotational and di€ usional relaxation times, which are easy to calculate, provide usef...

Molecular dynamics simulations of the rheology of normal decane, hexadecane, and tetracosane

Extensive nonequilibrium molecular dynamics simulations have been carried out for liquid decane, hexadecane, and tetracosane at densities corresponding to atmospheric pressure and near ambient temperatures. The strain-rate-dependent viscosity has been obtained for strain rates ranging over several orders of magnitude. At high strain rate, the viscosities for all alkanes studied here have simila...

Effective Interactions between Polyhedral Oligomeric Sislesquioxanes Dissolved in Normal Hexadecane from Molecular Simulation

Polyhedral oligomeric silsesquioxanes show promising applications as organic-inorganic nanocomposite building blocks that can be used, for example, to enhance the properties of polymeric materials. In this work radial distribution functions, potentials of mean force, and self-diffusion coefficients are obtained from molecular dynamics simulations for polyhedral oligomeric silsesquioxane (POSS) ...

Correlation of Liquid Viscosity at the Normal Boiling Point

The importance of liquid viscosity in chemical process design makes it one of the most measured transport properties. Nevertheless, of the 1893 compounds in the DIPPR 801 pure-component database, liquid viscosity and its temperature dependence (at 1 atm, or 0.1 MPa) have been predicted for nearly 50% of the compounds because no experimental data are available. Unfortunately, prediction methods ...
