As part of the improvement in numerical methods of two-phase flow, JAEA is underway to investigate CFD methods based on the VOF (Volume of Fluid) method. In the present work, we simulated the instability of the gas-liquid interphases between incompressible plane gas sheet and quiescent liquid showing an unstable mode of sinuous or varicose, using a VOF method solver available in the open source CFD code "OpenFOAM". The calculated results were found to agree reasonably well with the linear instability theory by Li. et al.. Furthermore, the effects of interface compression parameter and the number of mesh cells were investigated.
