Different patterns of drop size dependence of contact angles have been observed experimentally. Some investigators reported a decrease of contact angle with an increase in drop size, while others reported an increase. Still others reported that there is no drop size dependence of contact angles. The
Absence of drop size dependence of contact angles of sessile drop systems is sometimes observed in experiments. The contact angle data sometimes fluctuate periodically about a horizontal line. Moreover, in cases where a drop size dependence of contact angles exists, the contact angle data often scat
