Abstract

This article focuses on investigating the meniscus rise (capillary action) effect in nuclear magnetic resonance (NMR) spectroscopy for in situ vapor–liquid equilibrium (VLE) measurements of fluid mixtures. Using three-dimensional computational fluid dynamics (CFD) models calibrated and validated against high-resolution x-ray computed tomography (XCT) and NMR experiments, the study predicts how capillary diameter and fluid properties influence liquid-volume fraction and meniscus geometry inside NMR tubes with inserted capillaries. Results demonstrate that manipulating capillary geometry and bulk liquid volume can control the relative liquid-to-vapor signal ratio in NMR detection windows, improving peak resolution and reducing measurement uncertainties in multiphase VLE analyses. The combined experimental–numerical approach provides a framework for optimizing NMR configurations to enhance quantitative multiphase composition measurements in chemical process research.
