Based on an analytical formula of the Tolman length, some estimations of the Tolman length were obtained. The Tolman length is non-negative. The Tolman length of the fluid is zero while isothermal compression rate of the fluid is zero. The Tolman length is divergent at the critical point. The curvature dependence of surface tensions of spherical droplets can be further gotten based on this analytical formula of the Tolman length. The surface tensions increase as the radii of spherical droplets increase. Two estimations of the Tolman length are obtained based on Egelstaff–Widom formula and Sanchez’s equation. Based on the results of molecular dynamics simulations, it can be calculated that the value of dimensionless structure constant A of droplets consisted of argon molecular system is 1.9398 when the temperature is 96 K. An estimation of the Tolman length is obtained based on a relationship between the isothermal compressibility, liquid density and speed of sound in a liquid. |
