| Abstract: |
| The lattice Boltzmann potential model was firstly used to simulate the droplets impacting on solid surfaces. The flow state of droplets on solid surfaces and the effects of the impact parameters on the droplet impingement have been studied. It has been observed that surface wettability has a significant influence on the droplets impacting dynamics, the less of surface wettability, the easier to rebound and the faster of the recoiling speed. The higher of the impact speed and the smaller of the liquid viscosity, the bigger of the relative diameter is. In addition, the maximal relative diameter has linearity relation with the Weber number. Simulation results are consistent with the previous theory prediction and experimental results. |
