Abstract
In this work, water is captured as regular fluid with suspension of two types of hybrid nanoparticles, namely molybdenumdisulfide (MoS2) and graphene oxide (GO). The impact of Lorentz’s forces on mixed convective boundary-layer flow (BLF) is studied through an upright cylinder under the influences of thermal radiation. The shape factor is also assessed. The mathematical model for hybrid nanofluidis developed and, by implementing suitable similarity variables, the leading partial differential equations (PDEs) are altered into a non-linear ordinary differential equations (ODEs) system and then resolved through a bvp4c solver. The penetrations of varied parameters, such as thermal radiation, nanomaterials shapes (bricks, platelets, bricks and cylinders), magneto-hydrodynamics (MHD), and ratio parameters on the temperature and fluid velocity, along with the skin friction and the Nusselt number, are typified qualitatively via sketches. The opposing flow, as well as the assisting flow, is considered. The results indicate that the impact of hybrid nanofluid (HBNF) on the velocity and the temperature is more than nanofluid (NF). It is also scrutinized that the blade-shaped nanomaterials of hybrid nanofluid have a maximum temperature and brick-shaped nanomaterials have a low temperature. In addition, the friction factor and the heat transport rate decline due to the magnetic parameter and increase due to the shape factor. Moreover, the radiation uplifts the velocity and temperature, while the free stream Reynolds number declines the velocity and temperature. Finally, a comparison with available results in the literature are made and found in an excellent way. The ranges of constraints in this research are considered as: 0.01 ≤ λ ≤ 0.2 , 0 ≤ M ≤ 4 , 0 ≤ α ≤ 1.5 , 0 ≤ R d ≤ 1 , 1 ≤ Re a ≤ 3 , 0 ≤ ϕ 1 ≤ 0.1 and 0 ≤ ϕ 2 ≤ 0.003 .

Summary
Nanofluids and their importance have been influenced by many scientists and researchers due to several applications in numerous realistic processes, such as cancer treatment, cooling of electronic devices, the nuclear industry, drug delivery, etc. The field of magnetics on stagnationpoint flow containing water based TiO2 -Cu hybrid nanofluid through a stretched surface with shape factors was explored by Ghadikolaei et al [3] Their studies revealed that the nanoparticles that wereplatelet-shaped are more effective compared with other shapes. Iqbal et al [5] discussed the impact of water-based SiO2 nanoparticles and MoS2 -SiO2 HBNF from a curved stretched sheet under the impact of heat generation, magnetic field, shape factors, slip effect, and thermal radiation. Their results showed that the flow moves faster in the phenomenon of hybrid nanofluid compared to nanofluid.
