Three-dimensional computational multiphase fluid dynamics CMFD simulations are performed in order to estimate pressure gradients in slug flow gas non-Newtonian systems by gas injection. The estimated pressure reductions are compared with experimental data. Simulations were performed in an L-shaped pipe in order to maintain a stable single slug at all times, as this set up allows for the estimation of the pressure gradient along the slug. Calculations showed an excellent agreement between the simulation and experimental data. Shear thinning effects are also correctly modeled in this work.
