“…In another article, experimental studies on the nucleate pool boiling of aluminawater based nano-fluids on flat plate heater were performed by Nasresfahani et al [14]. They showed that, when the heating surface has a ratio of average surface roughness to the average diameter of nanoparticles much less than unity, the heat transfer coefficient of nano-fluid boiling reduces while critical heat flux (CHF) increases.…”

“…When fouling is formed on the surface, two possible cases can be considered. In the first case, the ratio of mean nanoparticle size to the average roughness of the surface is much more than unity [14] and in the second case, the ratio of nanoparticle size to the roughness of the surface is less than unity [25,26]. In this work, three nano-fluids with different particle size are utilized.…”

“…In fact, depending on the surface roughness and type of nanoparticles enhancement/deterioration of heat transfer coefficient can be seen for nano-fluids. Shahmoradi et al [11] performed experimental studies on nucleate pool boiling of alumina based aqueous nano-fluid on flat plate heater. They demonstrated that for boiling of nano-fluid (< 0.1 vol.%) on heating surface with ratio of average surface roughness to average diameter of particles much less than unity when boiling continue to CHF, the heat transfer coefficient of nano-fluid boiling reduces while critical heat flux (CHF) increases.…”

“…Diğer taraftan, Şekil 6'da görüldüğü üzere, saf su ile karşılaştırıldığında, çekirdek kaynama ısı transferi üzerinde nano akışkanların önemli bir etkisinin olmadığı görülmektedir. Araştırmacılar, katı yüzey üzerinde biriken nano partiküllerin yüzeyin morfolojisini ve ıslatabilirliğini önemli ölçüde değiştirebileceği rapor etmişlerdir [12][13][14][15][16][17][18]. Film kaynama bölgesinde sadece birkaç mikron kalınlığındaki buhar filmi, böylesi bir partikül birikmesinden etkilenebilir [19].…”

“…Şekil 8'de görüldüğü gibi, nano akışkan deneyleri sonrasında yüzey temas açısı önemli ölçüde azalmıştır. Bazı araştırmacılar da temas açılarında düşüş gözlemişlerdir ki bu durum yüzeydeki aktif buhar çekirdeklerinin sayısında düşüşe neden olmuştur [12,20,[24][25][26][27]. Araştırmacılar düşük partikül konsantrasyonlarında bile (<0.01vol.%) CHF değerinde %250'ye varan önemli artışlar gözlemişlerdir [28][29][30].…”
