Heat transfer through enhanced hydromagnetic mixed convection has the potential to be of long-term benefit in high-performance thermal equipment, hybrid fuel cell technologies, cooling systems for microelectronic devices, and subterranean cable networks. The purpose of this study was to investigate the influence of an inclined magnetic field thermal radiation and a heat source/sink on the flow and temperature behavior of an Aluminium oxide-Copper/water-based nanofluid in an undulating permeable enclosure enclosing a four-sided solid-block. A f inite volume technique is used to solve the given governing equations. In order to construct a discussion based on the results, streamlines and isotherm contours are employed to characterize the flow pattern and temperature distribution, respectively. The current findings, which show good agreement with those found in the earlier literature, confirm that the recommended approach is reliable. The analysis focuses on the influence of heat generation, heat source length, thermal radiation, porous medium porosity, and the dimensionless placement of the left heater factors on flow and heat transfer characteristics. The length of the heat source (B) of the fluid flow in the cavity is observed to increase everywhere except for the square solder block and shift the top of the wavy wall. The Nu m grows when the φ raises in thermal radiation. The average Nusselt number increases with increased porosity, although the rate of increase is faster in areas with higher heat flow
