Full TextAbstract
In the present study, the flattening and simultaneous solidification of a liquid droplet upon its impingement onto a solid surface has been numerically simulated and an extensive set of results has been generated to represent this complex deformation process. The numerical solution for the complete Navier-Stokes equations is based on the modified SOLA-VOF method using rectangular mesh in axisymmetric geometry. For the solidification part of the deformation process, based on a one dimensional Stefan problem in beat conduction, a numerical procedure has been developed. The results for the complete deformation process and the effect of some important input data including impact velocity, droplet diameter, viscosity, surface tension and contact angle have been discussed. Comparing our predictions with some available data reveals a good agreement, therefore, the model may be considered to be well suited for investigating the droplet deformation.
