Lattice Boltzmann pseudopotential multiphase modeling of transcritical CO2 flow using a crossover formulation

Abstract

This report summarizes our recent implementation of a crossover formulation in the lattice Boltzmann method and its application in modeling transcritical CO₂ sequestration in water-saturated porous media. A crossover enhancement of the Peng‑Robinson equation of state increases the accuracy in predicting fluid properties in transcritical conditions.
