Abstract

Purpose: To perform a numerical simulation of the impingement process, including flattening and simultaneous solidification, of a liquid droplet onto a solid surface. Methods: 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 heat conduction, a numerical procedure has been developed. Results: An extensive set of computations for different cases has been carried out to study the complete deformation prOCess and the importance of solidification in spreading process. The effect of solidification becomes more important for high Reynolds and low Stefan numbers. We found a good agreement betweenour results and the available data. Conclusions: The simultaneous solidification has an important effect on the impingement process in plasma spraying such that the two phenomena of flattening and solidification can not be studied separately.
