Various techniques have been employed by researchers with the aim to enhance the thermal performance of regular fluids such as water, kerosene oil etc. Nowadays the focus is on the hybrid nano materials as they are more effective in order to enhance the thermal conductivity of the fluids and liquid alloys as compared to nanofluids. This study is also performed with the objective of analyzing steady mixed convection flow near a 3D non-uniform vertical surface together with slips effects embedded in a porous medium with hybrid nano particles. The suspension under consideration is prepared in water to form MoS₂–SiO₂/water hybrid nanofluid by dissolving an inorganic compound Molybdenum disulfide (MoS₂) and silicon dioxide (SiO₂). The mathematical model describing the fluid flow has been formulated and similarity equations have been derived with the help of similarity transformations. The simulations of the obtained flow have been determined by employing bvp4c solver in MATLAB. The simulations for various physical parameters in the model demonstrate that incorporation of the hybrid nano particles in the fluid mixture result in higher heat transfer compared to the heat transfer produced by simple nanofluids. It is found that in order to obtain an efficient thermal system, the hybrid nano-particles should be considered in place of single type of nano particles. Moreover, the velocities of both the hybrid nano-fluids and simple nanofluids are enhanced by the mixed convection parameter however it is reduced by the porosity in both cases. It is also realized that an increment in the volume fraction of nano particles φ₁ corresponds to increase in heat transfer rate. Additionally, the temperature measurements are at its lowest for τ₂ while the maximum temperature is observed in case of solid volume fraction of nanoparticles φ₁. The heat transfer rate in MoS₂–SiO₂/H₂0 is better than that of MoS₂-H₂0. On the other hand, we can witness that the fluid velocity slows down by increasing the velocity power index parameter n. It is evident from investigation that hybrid nanofluids play a vital role in fluid transmission and higher temperature distribution is attained for nanofluid.
