پیش گویی کشش سطحی محلول های دو جزئی با استفاده از تئوری scaled particle theory (spt)
شیمی سطح، شاخه ایاز علمشیمیاست که به مطالعه واکنش های سطح و فصل مشترک بین دو فازمی پردازد و اهمیت زیادی در بسیاری از صنایع دارد. کشش سطحی به عنوان یکی از پارامترهای بسیار مهم سطح در این پروژه بررسی می شود. کشش سطحی نه تنها در تعیین کیفیت بسیاری از محصولات صنایع مختلف نظیر رنگ، مواد آرایشی، انواع پوشش ها، شوینده ها و... تأثیر دارد، بلکه در بسیاری از مراحل مهم در فرآیندهای تولید از جمله تجزیه، جذ...
15 صفحه اولScaled particle theory for hard sphere pairs. I. Mathematical structure.
We develop an extension of the original Reiss-Frisch-Lebowitz scaled particle theory that can serve as a predictive method for the hard sphere pair correlation function g(r). The reversible cavity creation work is analyzed both for a single spherical cavity of arbitrary size, as well as for a pair of identical such spherical cavities with variable center-to-center separation. These quantities l...
متن کاملLennard-Jones Energy Parameter for Pure Fluids from Scaled Particle Theory
By considering the fact that the surface tension of a real fluid arises from a combination of both repulsive and attractive forces between molecules, a new expression for the interfacial tension has been derived from scaled particle theory (SPT) based on the work of cavity formation and the interaction energy between molecules. At the critical temperature, the interfacial tension between c...
متن کاملFluids in random porous media: Scaled particle theory*
The scaled particle theory (SPT) is applied to describe thermodynamic properties of a hard sphere (HS) fluid in random porous media. To this purpose, we extended the SPT2 approach, which has been developed previously. The analytical expressions for the chemical potential of an HS fluid in HS and overlapping hard sphere (OPH) matrices, sponge matrix, and hard convex body (HCB) matrix are obtaine...
متن کاملScaled particle theory for hard sphere pairs. II. Numerical analysis.
We use the extension of scaled particle theory presented in the accompanying paper [F. H. Stillinger et al., J. Chem. Phys. 125, 204504 (2006)] to calculate numerically the pair correlation function of the hard sphere fluid over the density range 0< or =rhosigma(3)< or =0.96. Comparison with computer simulation results reveals that the new theory is able to capture accurately the fluid's struct...
