The behavior of the
pure substances during the condensation of liquid droplets in a supersaturated
vapor and, the mechanism of homogeneous nucleation of vapor to liquid droplets
that may occur as a result of large amplitude density fluctuations within the coexistence
line in the metastable region have been investigated. The free energy change
accompanying the formation of a critical water drop is calculated as a function
of droplet radius for various saturation ratios on the basis of Fisher’s model.
It is observed that a geometric term due to the fact that the surface of a drop
relaxes to spherical shape which reduces the total entropy associated with the
surface free energy, produces significant changes in total free energy change
of critical droplet formation.
Süperdoymuş bir buhar içinde damlacık oluşumu sırasında saf bir numunenin
davranışı ve yarı sıvı-gaz faz eğrisi altındaki kararlı bölgedeki büyük
genlikli yoğunluk dalgalanmaları sonucunda buhar fazından damlacıklar oluşumu
süreçleri araştırılmıştır. Fisher modeli temelinde, çeşitli doyma oranları
için, kritik su damlacıklarının oluşumu esnasındaki serbest enerji değişimleri
damlacık yarıçapının bir fonksiyonu olarak hesaplanmıştır. Damlacık yüzeyinin
küresel şekil alması ile yüzey serbest enerjisi ile bağlantılı olan toplam
entropinin azalmasını tanımlayan geometrik terimin kritik damlacık oluşumlarını
tanımlayan toplam serbest enerjide anlamlı değişmelere neden olduğu gözlenmiştir.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
