## Abstract Impaction on smooth solid substrates of drops formed by the dropβonβdemand (DOD) method was investigated over a wide range of impaction speeds (U~0~ = 2.21β12.2 m/s), surface contact angles (ΞΈ = 6β107Β°), and drop diameters (D~0~ = 40.8β50.5 ΞΌm). The experimental results were compared wi

A description of the entire configuration of liquid drops spreading over a previously wetted solid surface is given in the case of negligible evaporation and small Bond and Weber numbers. Two solutions are developed: an outer one which is valid in the bulk of the drop and an inner solution which app
There have been many experiments that have determined the wetting behavior of liquids on low-energy solid surfaces. These experiments show that, in general, the contact angle, theta, measured through the liquid, increases with increasing liquid-vapor surface tension, sigmalv. Surprisingly, in experi
