Thermophysical properties of the working fluid of a fluid-driven heat transfer system is the key parameter in determination of heat transfer performance of the system they were used. The nanofluids, nanoparticles containing colloidal suspensions, have been extensively used for performance enhancement in many applications, however, the nanoparticles cannot have both high thermal conductivity and good stability simultaneously. To provide these characteristics together, hybrid utilization of nanoparticles has emerged. In this numerical study, pool boiling heat transfer characteristics of dilute Fe+ZnO/deionized water hybrid nanofluid were investigated under low heat flux condition. The hybrid nanofluid suspension at the volumetric rate of 0.5% and Fe+ZnO combination of (50:50) were taken into account. For numerical simulations, Computational Fluid Dynamics approach and Volume-of-Fluid multiphase model were employed. Vapor volume fractions and velocity vectors in fluid medium were obtained for deionized water, and the hybrid nanofluid aforementioned. The start-up of the bubbles and departures with time were investigated for each working fluid. Under the same conditions, the start-up time of the boiling for deionized water and dilute hybrid nanofluid were observed as 468. and 441. seconds, respectively. The numerical findings also displayed that hybrid nanofluids can be used for pool boiling implementations in order to provide improved heat transfer characteristics.

Akışkanla çalışan bir ısı transfer sisteminin çalışma akışkanının termofiziksel özellikleri, kullanıldıkları sistemin ısı transfer performansının belirlenmesinde anahtar parametredir. Nanokışkanlar, nanoparçacıklar içeren koloidal süspansiyonlar, birçok uygulamada performans iyileştirme amacıyla yaygın olarak kullanılmıştır, ancak nanoparçacıklar aynı anda hem yüksek ısıl iletkenlik hem de iyi derecede kararlılık sağlayamamaktadır. Bu özellikleri bir arada sağlamak için nanoparçacıkların hibrit kullanımı ortaya çıkmıştır. Bu sayısal çalışmada, seyreltik Fe + ZnO/saf su hibrit nanoakışkanın havuz kaynama ısı transfer özellikleri düşük ısı akısı koşulu altında incelenmiştir. Analizlerde, %0,5 hacimsel oranda hibrit nanoakışkan süspansiyonu ve Fe+ZnO kombinasyonu (50:50) olarak dikkate alınmıştır. Sayısal simülasyonlar için Hesaplamalı Akışkanlar Dinamiği yaklaşımı ve Akışkan Hacmi çok fazlı modeli kullanılmıştır. Hem saf su hem de bahsi geçen hibrit nanoakışkan için akışkan ortamındaki buhar hacmi fraksiyonları ve hız vektörleri elde edilmiştir. Her bir çalışma akışkanı için kabarcıklanma başlangıcı ve zamanla bunların yüzeyden ayrılışları incelenmiştir. Aynı şartlar altında saf suyun ve hibrit nanoakışkanın sırasıyla 468. ve 441. saniyelerde kaynamaya başladığı gözlemlenmiştir. Sayısal bulgular, hibrit nanoakışkanların iyileştirilmiş ısı transfer özellikleri sağlamak için havuz kaynama uygulamalarında kullanılabileceğini göstermiştir.
