Calculation of the Isothermal Compressibility of Yukawa Fluids Using a Two-Step Approximation for the Radial Distribution Function
摘要
Abstract
Using a two-step approximation for the radial distribution function, an analytical expression was obtained that makes it possible to calculate the isothermal compressibility coefficient of a Yukawa fluid for different values of nonideality and screening parameters. The calculation results are consistent with data from molecular dynamics numerical simulation.
