Spreading Time of Liquid Droplets Impacting on Non-wetting Solid Surfaces

The spreading time that a droplet takes to reach its maximum spreading state is a parameter of paramount importance. We study the impact of a liquid droplet on a super-hydrophobic surface. A contact angle of \(\theta =170^{\circ }\) is used as the numerical input for the non-wetting property of the surface. Numerical simulations to understand the effects of initial impact conditions on spreading time of liquid droplets onto solid surfaces are conducted in a regime where \(1
