“…Furthermore, in the previous experimental researches, it has been shown that the suspended nanoparticles in the base liquid decrease the radius of the bubble and, therefore, more active sites on the heating surface occur. Consequently, the boiling heat transfer coefficient increases, which is consistent with the present results (Raveshi et al, 2013;Kim and Kim, 2009;Yang and Liu, 2011). …”

Due to significant improvement of thermal performance and other properties of nanofluids, this group of liquids is in high demand. According to the literature, the effect of nanoparticles on boiling heat transfer enhancement or degradation is not the same among different investigations. In the present article, the pseudo-potential multiphase lattice Boltzmann method is used to simulate nucleate pool boiling with two different fluids: a pure liquid and a nanofluid. The current results indicate that the contact angle is the same for both the fluid and nanofluid when the vapor bubble detachment occurs. Also, bubble departure diameter is greater in the base liquid while bubble release frequency is higher in the nanofluid. In brief, the present results demonstrate that using a nanofluid instead of its base fluid will increase the boiling heat transfer coefficient.

“…Raveshi et al [83] investigated the nucleate boiling heat transfer of Al 2 O 3 /water-EG nanofluids on the upper surface of a Cu cylinder under atmospheric pressure in a cylindrical Pyrex glass container (Ø100x300mm). It was reported that the nanofluids of 0.75 vol% optimum nanoparticles concentration exhibited a maximum enhancement in boiling HTC up to 64%.…”

“…They explained a 91% enhancement in CHF. Raveshi et al (2013) also clarified a 64% enhancement in the heat transfer coefficient of water-EG based Al 2 O 3 nanofluids on a copper cylinder of 40 mm diameter. As a result, a considerable increment in the CHF value of present nanofluid (103%) is obtained in this study.…”

The present paper focuses on an experimental study of pool boiling characteristics of cerium oxide (CeO 2 , 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.Keywords: Cerium oxide, critical heat flux, heat transfer, nanoparticles, pool boiling ÖZET: Bu çalışma, atmosfer basıncı altında yatay bir bakır plaka üzerinde cerium oksit (CeO 2 , 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.Anahtar kelimeler: Cerium oksit, havuz kaynama, ısı transferi, kritik ısı akısı, nano partikül
