摘要:

本文用密度泛函方法研究了离子流体受限原始模型的气液界面。应用的理论包括静电贡献的自由能功能所产生的散装能量状态方程和平均球近似的限制原始模型,以及缔合的贡献,由于对离子的形成。我们比较的密度分布和表面张力的值与以前的理论方法。

英文摘要:

We investigate the liquid-vapor interface of the restricted primitive model for an ionic fluid using a density functional approach. The applied theory includes the electrostatic contribution to the free energy functional arising from the bulk energy equation of state and the mean spherical approximation for a restricted primitive model, as well as the associative contribution, due to the formation of pairs of ions. We compare the density profiles and the values of the surface tension with previous theoretical approaches.
