In the present study, maximum spreading diameter of a droplet impacting with spherical particle is numerically studied for wide range impact conditions: Weber number (We) 0–110, Ohnesorge (Oh) 0.001 3–0.786 9, equilibrium contact angle ( ? eqi ) 20°–160°, and droplet-to-particle size ratio (?) 1/10–1/2. A total 2600 collision cases are simulated to enable systematic analysis prepare large datas...
