N2 - The Volume of Fluid (VOF) and Immersed Boundary (IB) methods are two popular computational techniques for multi-fluid dynamics. To help shed light on the performance of both techniques, we present accuracy assessment including interfacial geometry, detailed and global transport characteristics. The investigations include the simulations of a droplet under static equilibrium and a droplet rising due to gravity for Re≤1000. Different surface tension force models are also studied and improved models for both VOF and IB are presented. An improved curvature model for VOF is also presented. With the improved treatments incorporated, both IB and VOF perform comparably for the droplet dynamics with varying flow parameters and properties.
