Abstract Radiative behavior of nanomaterial with different shapes of nanoparticles within a permeable domain is simulated with an innovative approach. To predict the characteristics of Al2O3–H2O, shape factor impact has been considered. Outputs were extracted for various buoyancy, Hartmann and radiation. Outcomes indicate that domination of conduction mode occurs in existence of magnetic force. Augmenting temperature gradient can be seen for greater Rd. CVFEM has been involved to obtain and discuss impacts of all the governing parameters. The graphical outcomes demosntare that N uave reduces owing to a significant augmentation in Lorentz term. A converse behavior has been observed due to an augment in Ra and Rd. Noslip case has been considered to generate the numerical and graphical results. The present results show many new behaviors that warrant further study especially non-Newtonian fluid models.

Introduction Nanofluid was taken into account as an efficient fluid to transport heating, as it managed to illustrate its capability to improve temperature compared to the pure fluids. Such system can be presumed as a proper system for solar water heating systems, not suffering taxing challenges in pipes as well as it leads to lower rate of pressure drop. The boundary conditions, stream geometry and fluid thermic conductivity can be altered to increase convective heat transfer in a passive way. To achieve such target, various * Quang‑Vu Bach [email protected] 1

methods were improved to grow the heat transfer of fluid. So many scientists and researchers significantly endeavored for improving the fluid thermic conductivity. One of the popular methods to obtain that goal was suspending different sizes of solid particles in fluid thanks to their higher level of thermic conductivity than the liquids; however, the possible of becoming out of their suspension phase in not appropriate due to their large size and high density. During the past years, nanotechnology is the new passive method to deal with cooling problems. The primary aim of this technique is to enhance conduction. Therefore,
