A hexagonal plate simulated snow particle is exposed to an airflow containing water droplets in a vertical wind tunnel. The motion of the droplet around the plate is determined by stereoscopic analysis in order to find the trajectory grazing the model. The collection efficiency thus obtained is most similar to that of sphere in Langmuir and Blodgett's results but our value seems to be larger than all of their collection efficiency and to have finite value in the region of K≤1/12 where Langmuir and Blodgett's collection efficiency of sphere becomes zero.
