Nonlinear Radiative Heat Flux and Viscous Dissipation Passing Through a Rotating Disk

This study investigates the significant influence of various flow parameters on hybrid nanofluids and ternary hybrid nanofluids, modeled as non‐Newtonian fluids with symmetric behavior, an essential characteristic in advanced heat transfer applications. The analysis is conducted within the framework of steady, two‐dimensional flow over a rotating disk, incorporating the effects of nonlinear thermal radiation and sticky (viscous) dissipation. The governing partial differential equations are transformed into a system of ordinary differential equations (ODEs) using appropriate similarity transformations. These equations are solved numerically using the Runge–Kutta–Fehlberg method along with the shooting technique through MATLAB 2021(a). Additionally, asymptotic solutions for the wall shear stress are obtained to validate the numerical results. The impact of key physical parameters on velocity, temperature, and thermal performance is examined through detailed graphical illustrations. The results reveal that increasing magnetic field strength leads to a noticeable suppression of velocity profiles, while nonlinear current emission enhances the Nusselt number, temperature distribution, and flow intensity, and concurrently reduces local skin friction.
