N2 - The effect of nanoparticle volume concentration on the thermo-physical characteristics of hybrid nanofluid has been a major area of study. Since hybrid nanofluid combines the chmical and physical properties of nanoparticles in a useful way, they overcome the limitations of mono nanofluids. The goal of this work is to examine how the Cu-Al2O3 nanoparticles affect the thermal conductivity, dynamic viscosity and rheological characteristics of kerosene oil-based hybrid nanofluids. The focus on this study is to analyze the magnetized hybrid nanofluid flow over a stretching/shrinking cylinder with the influence of different physical effects. For this, a mathematical model of a hybrid nanofluid is formulated in the form of PDEs. Then these PDEs are converted into ODEs by applying similarity conversion and tackled numerically. To understand the flow behavior, friction drag enhancement, thermal distribution, and heat transport phenomenon of Cu-Al2O3/kerosene oil, the graphical results are sketched. The results show that nanoparticle inclusion boosts the skin friction coefficient and heat transport rate. Here, ϕ1, ϕ2 symbolize the Copper ϕCu and Aluminum Oxide ϕAl2O3 volume fractions, respectively. It is discovered that the values of Re1/2Cf and Re−1/2Nu grow when the values of nanoparticles volume fractions ϕ1, ϕ2 increase. Further, increasing magnetic strength lowers the fluid velocity and increases the thermal distribution of the liquid. Additionally, the temperature of the liquid is increased by rising Biot number and thermal radiation, respectively.
