Gas-shear-thinning liquid two-phase flows in a two-dimensional rectangular channel are numerically simulated. Shear-thinning liquid is modeled by the Carreau model, and the deforming boundary separating the gas and the liquid is numerically modeled using Efficient Least Squares VOF Interface Reconstruction Algorithm (ELVIRA). It is shown that the flow patterns of gas-shear-thinning liquid two-phase flow are greatly influenced by the local change in the viscosity. In the case of gas-shear-thinning liquid two-phase flow, it is difficult to predict the flow patterns in the rectangular channel. From a practical standpoint, design, operation and scale-up processes are discussed for gas-shear-thinning liquid two-phase flow system.
