摘要

数学关系已经发展为描述流体渗透到一组均匀固体球体的空隙空间。初始渗透或“突破”压力所需的压力是根据球形模型的孔隙度和流体的接触角来定义的。计算数据涵盖孔隙度47.64% ~ 25.95%,接触角90°~ 180°。这些关系允许根据标准汞渗透和孔隙度数据确定颗粒半径。

Mercury porosimetry—breakthrough pressure for penetration between packed spheres

The mathematical relationships have been developed for describing the penetration of fluids into the void spaces of a collection of uniform solid spheres. The pressure required for initial penetration or “breakthrough” pressure is defined in terms of the porosity of the spherical model and the contact angle of the fluid. Calculated data, covering the porosity range of 47.64% to 25.95%, and contact angles of 90° to 180°, are presented. These relationships allow the determination of particle radius from standard mercury penetration and porosity data.
