Abstract
(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... (More)
