Abstract
The free convective hybrid nanofluid (Fe3O4+MWCNT/H2O) magnetized non-Darcy flow over a porous cylinder is examined by considering the effects constant heat source and uniform ambient magnetic field. The developed coupled PDEs (partial differential equations) are numerically solved using the innovative computational technique of control volume finite element method (CVFEM). The impact of increasing strength of medium porousness and Lorentz forces on the hybrid nanofluid flow are presented through contour plots. The variation of the average Nusselt number (Nuave) with the growing medium porosity, buoyancy forces, radiation parameter, and the magnetic field strength is presented through 3-D plots. It is concluded that the enhancing medium porosity, buoyancy forces and radiation parameter augmented the free convective thermal energy flow. The rising magnetic field rises the temperature of the inner wall more drastically at a smaller Darcy number. An analytical expression for Nusselt number (Nuave) is obtained which shows its functional dependence on the pertinent physical parameters. The augmenting Lorentz forces due to the higher estimations of Hartmann retard the hybrid nanoliquid flow and hence enhance the conduction.
Highlights
The enhancement of heat energy transmission rate is an attractive research topic due to its central importance in heat energy technology like heat reservoirs, electronic cooling, solar collectors, nuclear reactors cooling, and heat exchangers and so on

Numerical modeling on hybrid nanomaterial migration considering MHD effect have been explored by Taylor et al [21], Hamza and Hafiz [22], and Said et al [23]
Summary
The enhancement of heat energy transmission rate is an attractive research topic due to its central importance in heat energy technology like heat reservoirs, electronic cooling, solar collectors, nuclear reactors cooling, and heat exchangers and so on. Rashidi and Nezamabad [9] experimentally examined the carbon nanotubes nanofluids thermal energy transfer coefficient by considering the impact of constant heat flux. Hayat and Nadeem [28] studied the thermal energy transfer properties of Ag-CuO/water nanoliquid They obtained that, hybrid nanoliquid shows a superior heat transfer rate in contrast with the ordinary nanofluid. Usman et al [29] examined the hybrid nanoliquid (Cu-Al2O3/water) movement over a porous field by seeing the effects of variable thermal conductivity and nonlinear radiation by using LSM. Numerical modeling on hybrid nanomaterial migration considering MHD effect After gaining the impetus from the above research studies, we want to analyze the nonDarcy hybrid nanofluid motion over a spongy cylinder by seeing the impacts of the heat source and ambient magnetic field. The main research outcomes are concluded in the last section
