This reported work studies the dynamics of a moderately viscous Taylor droplet in a 500 μm diameter circular microchannel. The focus is on the dynamics within the viscoinertial regime, and the study is performed numerically using the isoAdvector volume of fluid available in OpenFOAM v2012. A 2D axisymmetric domain is chosen and validated against experimental results in the visco-inertial regime from the literature. Taylor droplets of viscosity ratio (defined as dispersed phase to continuous phase) in the range of 0.5 to 5 are considered. The influence of the viscosity ratio on the droplet velocity, film velocity, internal circulation within the droplet, and film thickness is analyzed. A new film thickness equation is proposed for the viscoinertial regime. The proposed equation accurately predicts the present study and performs well with the available experimental film thickness data from the literature.
