Abstract

The paper presents results of experimental research that enables estimation of the effect of surrounding parameters on the surface wetted by a liquid droplet. Surrounding is composed of a system of a solid body surface and gas phase. In research, liquid droplets were introduced to the surrounding, as understood above. Dynamic spreading of droplets of water, aniline, and benzene, respectively, was considered in the paper. Analysis concerned the process of droplet spreading on three kinds of wall surfaces, that is, for surfaces made of: 1H18N9 stainless steel, CuCr1Zr copper alloy, and ordinary glass, respectively. The surfaces were characterized with various values of roughness.
