This research develops a framework to simulate multiphase flows with surface tension. Two open-sources are coupled to achieve this goal: interface reconstruction library (IRL), a library of the volume of fluid (VOF) scheme, and PeleLM, a reacting Navier-Stokes equation solver. In addition to the coupling, surface tension is implemented using the continuum surface model (CSF) along with the improved height function technique. The coupling produces spurious errors in the volume fraction field. The spurious error is corrected by geometric consideration, which improves the numerical stability and accuracy. With the developed framework, multiple validation simulations are conducted. The validation simulations are (i) translations and rotations of Zalesak’s disk, (ii) three-dimensional deformations of a sphere droplet, (iii) a stationary circular droplet with surface tension, and (iv) an oscillating elliptical droplet. Quantitative comparisons show that the shape errors of Zalesak’s disk and 3D deformation case show comparable errors with other solvers. The pressure inside the stationary droplet is well maintained within 3.6 % compared to the theoretical value. For the oscillating elliptical droplet case, the oscillation period is within 6.7% compared to the linear theory.
