Development of a Mechanistic and Data-Driven Model for Multiphase Flow Leak Detection in Pipeline by Barooah, Abinash

“…The effect of different pressure constraints, pipe length, pipe diameter, two-phase fluid rheology, leak diameter, leak location, outlet liquid volume fraction, and flowing liquid hold-up on leak size, pressure, and flow rate is analyzed. Decreasing the liquid fraction in the outlet section of the leak leads to a slight increase (6% average) in the inlet mass flow rate and a significant decrease (50% average) in the outlet mass flow rate for fixed pressure constraints, resulting in an increased leak flow rate, pressure, and density. …”

Influence of natural gas composition on adsorption in calcite Nanopores: A DFT study by Elbashier E.

“…Compared to the flat surface, for both molecules, CH4 and CO2, the interaction energy of the molecule with the nanopore could increase to more than five times depending on pore radius and molecule type. Additionally, in all cases, CO2 has a greater affinity to the surface than CH4; thus, it is more affected by the surface curvature and energy. …”
