Numerical study of droplet splashing in a CIP-based model

A multiphase model CIP-ZJU (Constrained Interpolation Profile Method in Zhejiang University) is developed, which is applicable of simulating free surface flow including liquid splashing, wave breaking and overturning. Numerical simulations are performed with a Constrained Interpolation Profile(CIP)-based method adopted as the base flow solver combined with an enhanced VOF (Volume of Fluid) type scheme as free surface capturing method. To assess the algorithm and its versatility, drop impact onto flat liquid film and water entry of cylinders are simulated. Good agreement is obtained in comparing computational results with experimental data. It is demonstrated that many typical features in complex flow patterns can be captured in the present numerical model.
