  • Dynamic wetting phenomena of droplets are widely observed in nature and industrial production, the numerical research of which needs a solution of singularity and a correct model of the dynamic contact angle. Based on the phase field method (PFM) and the modified dynamic contact angle model, a 2-phase flow numerical method with dynamic wetting effects was developed, and the related program was realized on the OpenFOAM platform. The dynamic process of droplets impacting on a wall was simulated, and the comparison of the computation results of different contact angle models was conducted. The results indicate that the contact angle model influences the dynamic wetting process simulation significantly; the results of the proposed method are in good agreement with those of the experiment, which shows the proposed method is effective in the simulation of dynamic wetting phenomena.
