ABSTRACT The primary objective of the study is to investigate the impact of a hybrid nanofluid, consisting of a combination of and beryllium copper nanoparticles in water, as it flows through a wedge with a nonlinear heat source. The model incorporates the factors of activation energy, radiative heat flow, and chemical reaction. The partial differential equations are made dimensionless through the use of a similarity transformation. The Runge–Kutta fourth‐order (RK4), along with the shooting approach and MATLAB software, is employed to solve these equations numerically. The simultaneous study of these integrated physical phenomena for an –BeCu hybrid nanofluid across a wedge with convective heating is unprecedented. Moreover, boundary conditions are employed to construct graphs and ascertain the behavior of temperature, concentration, and velocity profiles. The impact of different physical parameters on the velocity, temperature, and concentration profiles is depicted graphically. Significant relationships between parameters and flow characteristics were found in the study, which are in good agreement with previous research under restricting circumstances. The effects of magnetic field, radiation, and activation energy on transport phenomena are highlighted through the tabulation and analysis of numerical results for local skin friction, Nusselt number, and Sherwood number.
