Abstract
Foam viscosity is a key property to predict the foam flow in narrow channels and porous media. In this study, we investigated the effects of foam quality and temperature on the dynamic foam viscosity and how modifying the composition of colloidal system can alter the foam rheology. It was shown that the addition of nanoparticles and polymer can improve the foam stability at high-temperature conditions and increase the foam apparent viscosity. The results confirmed the foam apparent viscosity can be predicted using a power law model and the flow consistency index of the foam is a strong function of temperature and foam quality, while changes in the power law index with the variation in temperature and foam quality is insignificant.Finally, to predict the foam apparent viscosity, 3-D plots for the flow consistency and power law indices can be generated as a function of foam quality and temperature.
