Simulation of droplet spreading, splashing and solidification using smoothed particle hydrodynamics method

Spreading, splashing and solidification of yttria stabilized zirconia (YSZ) droplet after inclined impact are simulated by smoothed particle hydrodynamics. The artificial heat model has been improved and a simple solidification model is included. It is found that the droplet splashes when the impact angle is less than 44 degrees with the Reynolds number of 3535. Otherwise the droplet will deposit. The result is in good agreement with the theoretical prediction. The temperature distribution and solidification interface movement during the droplet impacting on an inclined surface are presented. The flattening ratio is found to increase with the impact angle. (c) 2007 Elsevier Ltd. All rights reserved.
