Our study has been investigated nanofluids' heat transfer performance in a wavy microchannel using theoretical and computational fluid dynamics. Al2O3, CuO, Fe2O3, TiO2 and SiO2 have been used in the calculations as nanoparticles. Volumetric nanoparticle ratios in the nanofluid are 1%, 2%, 3% and 4%. Outlet temperatures, Nusselt number, thermal conductivity efficency and convective heat transfer coefficients of nanofluids at 100, 250, 500 and 1000 Reynolds numbers have been investigated. It observed that the heat transfer performance increased thanks to the increasing Reynolds number and the increasing percentage volumetric nanoparticle ratio.

Çalışmada, teorik analiz ve hesaplamalı akışkanlar dinamiği kullanılarak dalgalı mikrokanalda nanoakışkanların ısı transfer performansı araştırılmıştır. Al2O3, CuO, Fe2O3, TiO2 ve SiO2 nanopartikül olarak hesaplamalarda kullanılmıştır. Nanopartiküllerin nanoakışkan içerisindeki hacimsel oranı sırasıyla 1%, 2%, 3% ve 4% şeklindedir. Nanoakışkanların 100, 250, 500 ve 1000 Reynolds sayısında çıkış sıcaklıkları, Nusselt sayısı, termal iletkenlik verimliliği ve termal taşınım katsayıları incelenmiştir. Artan Reynolds sayısı ve artan hacimsel nanoparçacık oranı sayesinde ısı transfer performansının arttığı gözlemlenmiştir.
