Numerical study of the flow of R1270-based nanorefrigerants in a circular tube subject to uniform heat flux

In this work, turbulent convective heat transfer of propylene (R1270)-based nanorefrigerant in a circular tube with a uniform heat flux of 20 kW/m2 is numerically investigated using different types of nanoparticles namely Al2O3, CuO, SiO2 and ZnO with a volume concentration ranging from 0 to 5%.
