Düzlemsel yüzeylerde damlacıkların kontakt açılarının ve ıslatma özelliklerinin incelenmesi

In this thesis, we have studied contact angle behavior of droplets on ideal and rough surfaces. We have examined contact angles of droplets on both homogeneous rough surfaces and heterogeneous rough surfaces. Then, we have studied how the contact angles of droplets change if we apply an external potential to the surface where the droplet rests. Splitting of a droplet has also been studied. To do that, we have re-derived some formulas and with the help of these formulas we have figured out how to split droplets. Also, we have calculated the electrostatic forces and capacitive energies on an ewod-actuated droplet. Finally, we have calculated the forces acting on the liquid-droplet interface of a droplet which is immersed in a liquid. These calculations have been done for three different cases.
