The present paper focuses on an experimental study of pool boiling characteristics of cerium

oxide (CeO2, ceria) nano-suspension on a horizontal flat copper surface at atmospheric pressure. The nanofluid

suspension is prepared by a two-step method and stabilized using Na-citrate, pH setting and ultrasonic vibration

as well. The effect of applied heat flux to the boiling surface on pool boiling heat transfer coefficient (HTC) of

cerium oxide nanofluid is experimentally examined and briefly discussed. The results illustrate that the pool boiling

HTC increases with using cerium oxide nanofluid as working fluid. Also, the results show that the critical heat flux

for cerium oxide nanofluid having 0.1 vol.% nanoparticle concentration improves up to 103% compared with the

deionized water.

Öz

Bu çalışma, atmosfer basıncı altında yatay bir bakır plaka üzerinde cerium oksit (CeO2, ceria) nanosüspansiyonunun

havuz kaynama karakteristiklerinin deneysel olarak incelenmesi üzerine gerçekleştirilmiştir.

Nano akışkan süspansiyonu iki adım metodu ile hazırlanmıştır ve Na-citrate ilavesi, pH ayarı ve ultrasonik titreşim

uygulanarak kararlı hale getirilmiştir. Cerium oksit nano akışkanının havuz kaynama ısı transfer katsayısı üzerine

kaynama yüzeyine uygulanan ısı akısının etkisi deneysel olarak incelenmiş ve sonuçlar tartışılmıştır. Deneysel

sonuçlar, iş yapan akışkan olarak cerium oksit nano akışkanının kullanılması ile havuz kaynama ısı transfer

katsayısının arttığını göstermiştir. Ayrıca elde edilen sonuçlar, de-iyonize su ile karşılaştırıldığında, %0.1 hacimsel

konsantrasyona sahip cerium oksit nano akışkanı için kritik ısı akısında %103 artış olduğunu göstermiştir.
