Abstract The flow at a time-independent separable stagnation point on Riga plate under thermal radiation and electro-magnetohydrodynamic settings is examined in this research. Two distinct base fluids-H 2 O C H 6 TiO nanostructures develop the nanocomposites. problem incorporates equations of motion energy along with unique model for viscosity conductivity. Similarity components are then used to reduce these calculations. Runge Kutta (RK-4) function yields simulation result, which displayed graphical tabular form. For both involved fluid theories, nanofluids profiles relating relevant aspects computed analyzed. According findings research, heat exchange rate significantly higher than model. As volume percentage nanoparticles rises, velocity field degrades while temperature distribution improves. Moreover, greater acceleration parameters, / has highest coefficient whereas skin friction coefficient. key observation that nanofluid little performance nanofluid.
