The present study examines the effect of the Hiemenz stagnation point and magnetic field on the ternary nanofluid flow on the permeable stretching/shrinking surface. Ternary nanofluid composites are formed by dissolving silicon dioxide (SiO2), aluminum oxide (Al2O3), and titanium dioxide (TiO2) in base fluid water (H2O), and applying these nanoparticles to the water (base fluid) will enhance heat transfer. Furthermore, it studied the heat transmission process using variable thermal conductivity of the thermal radiation. It is noted that there is a lack of study on ternary nanofluids in the circumstances of the Hiemenz stagnation point and radiation with porous media. The novelty of the present problem is to examine the influence of magnetic field and radiation over ternary nanofluid flow. Governing equations of velocity and temperature are converted to a set of nonlinear ordinary differential equations via suitable transformations, and the obtained equations are solved using the boundary conditions, energy equation with radiation effect solved analytically by using error function and hypergeometric function. Significant physical characteristics like mass transpiration, Schmidt number, magnetic parameter, and thermal radiations, volume fraction can be discussed using the graphical analysis. The outcomes of the investigation reveal that increasing the magnetic field enhances temperature and decreases the momentum of the fluid flow. Increasing the volume fraction and thermal radiation increases the thermal boundary layer, and velocity decreases by increasing in inverse Darcy parameter, ternary nanofluids significantly increase thermal conductivity and can be used as coolants for radiators due to their improved thermal performance. Finally, adding a magnetic field causes a moving conductive fluid to conduct current, which in turn creates forces on the fluid. This is particularly useful for green and sustainable development in a variety of engineering applications as well as biomedical disciplines like medication delivery and energy efficiency.

Abstract
The present study examines the effect of the Hiemenz stagnation point and magnetic field on the ternary nanofluid flow on the permeable stretching/shrinking surface. Ternary nanofluid composites are formed by dissolving silicon dioxide (SiO2), aluminum oxide (Al2O3), and titanium dioxide (TiO2) in base fluid water (H2O), and applying these nanoparticles to the water (base fluid) will enhance heat transfer. Furthermore, it studied the heat transmission process using variable thermal conductivity of the thermal radiation. It is noted that there is a lack of study on ternary nanofluids in the circumstances of the Hiemenz stagnation point and radiation with porous media. The novelty of the present problem is to examine the influence of magnetic field and radiation over ternary nanofluid flow. Governing equations of velocity and temperature are converted to a set of nonlinear ordinary differential equations via suitable transformations, and the obtained equations are solved using the boundary conditions, energy equation with radiation effect solved analytically by using error function and hypergeometric function. Significant physical characteristics like mass transpiration, Schmidt number, magnetic parameter, and thermal radiations, volume fraction can be discussed using the graphical analysis. The outcomes of the investigation reveal that increasing the magnetic field enhances temperature and decreases the momentum of the fluid flow. Increasing the volume fraction and thermal radiation increases the thermal boundary layer, and velocity decreases by increasing in inverse Darcy parameter, ternary nanofluids significantly increase thermal conductivity and can be used as coolants for radiators due to their improved thermal performance. Finally, adding a magnetic field causes a moving conductive fluid to conduct current, which in turn creates forces on the fluid.
