متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
A simple molecular thermodynamic theory of hydrophobic hydration
A recently developed microscopic model for associating fluids that accurately captures the thermodynamics of liquid water @Truskett et al., J. Chem. Phys. 111, 2647 ~1999!# is extended to aqueous solutions with nonpolar species. The underlying association model incorporates the highly directional and open nature of water’s hydrogen-bond network, and, as a result, captures a number of the distin...
متن کاملA molecular dynamics study of Li-doped borate glasses
The objective of this work is to investigate the effect of alkali content and temperature on the microstructure of lithium borate glasses, xLi2O · (1 − x)B2O3. We have applied the molecular dynamics technique with Ewald summation and periodic boundary conditions to a collection of ca. 256 particles confined within a primitive cubic cell and interacting through a BornMayer-Huggins type of potent...
متن کاملThermodynamic Identities and Symmetry Breaking in Short-Range Spin Glasses.
We present a technique to generate relations connecting pure state weights, overlaps, and correlation functions in short-range spin glasses. These are obtained directly from the unperturbed Hamiltonian and hold for general coupling distributions. All are satisfied in phases with simple thermodynamic structure, such as the droplet-scaling and chaotic pairs pictures. If instead nontrivial mixed-s...
