摘要:The phenomena and behaviors of different droplets impacting on the solid
   flat surface were observed and recorded with a high-speed camera, then
   dynamic contact angle, dynamic spreading coefficient and dimensionless
   height were measured and the effects of the parameters on the droplet
   impacting were studied. The results show that during the spreading
   process, the higher concentration of droplet has bigger dynamic contact
   angles, while during the receding process, the dynamic angles of the
   brine are smaller than that of the pure water. Spread coefficient
   decreases with rise of the concentration of droplet. With increase of
   droplet diameter, the maximum spreading coefficient increases, and the
   oscillation frequency of droplet decreases. For the bigger droplet, the
   concentration has little effect on the dynamic spreading characteristics
   during the spreading process. When the impact velocity increases, the
   spreading coefficient rises, and the period of receding to the minimum
   spreading coefficient is shortened. Compared to the impact velocity, the
   droplet diameter is more likely to affect the oscillation frequency of
   the droplet.
