ABSTRACT Ternary hybrid nanofluids made of AA7072, AA7075, and Al 2 O 3 dispersed in diathermic oil have a high thermal carrying capacity and would be useful in the more sophisticated industrial setting of heat transfer. The purpose of this work is to investigate the mass and heat transfer rates of ternary hybrid nanofluids across a cone and wedge geometry under various physical parameters, including radiation, heat source, suction, and porous. The model takes into account steady, laminar, incompressible flow with no‐slip boundary conditions and takes into account effects like magnetic field, suction, thermal radiation, chemical reaction, and porous medium, along with Tiwari–Das model relations, which are used to evaluate the ternary nanofluid's thermophysical characteristics. The governing equations of nonlinear boundary value problems (BVPs) are numerically solved, and the results of heat and mass transfer are obtained using the bvp5c solver in MATLAB software. The findings show that the cone geometry has better heat and mass transfer than the wedge geometry because the thermal and concentration gradients are stronger. Additionally, suction improves the boundary layer's stability, whereas magnetic and radiative interactions have a considerable impact on temperature profiles; it was found that raising these parameter values causes an increase in temperature profiles.
