Extensive first-principle molecular dynamics simulations are performed to study the phase behavior of metastable liquid Si at negative pressure. Our results show that high-density (HDL) and HDL-vapor spinodals indeed form a continuous reentrant curve liquid-liquid critical point seems just coincide with its minimum. The line density maxima also has strong tendency pass through this behaviour therefore tends be critical-point-free scenario rather than second-critical-point one based on SW potential.
In this research, thermal modeling has been done to investigate the effect of nanofluid on performance linear parabolic collector. Therminol vapor/liquid phase fluid (VP-1) used as a base fluid; iron oxide nanoparticles have produce mono-nanofluid; and multi-walled carbon nanotubes nanocomposite hybrid nanofluid. The flow inside absorber tube collector is assumed be turbulent. results show that when mono-nanofluid are used, energy exergy efficiencies higher than those for conditions using...
Abstract The relationship between structural order and water-like anomalies in tetrahedral liquids is still open. Here, first-principle molecular dynamics are performed to study it metastable liquid Si. It found that T - P phase diagram, there indeed exists a anomaly region, which encloses density but not diffusivity anomaly. This consistent with of SW Si BKS SiO 2 different from SPC/E water. Two-body excess entropy can neither capture the diffusivity, structural, anomalies, as two-scale...
