Mixed Convection Flow for Hybrid Nanofluid over a Rotating Paraboloid Surface with Thermal Radiation

The flow of a hybrid nanofluid in magnetohydrodynamics (MHD) across a rotating parabolic surface is examined in this work. A system of ordinary differential equations (ODEs) is created from the governing partial differential equations (PDEs). The main goal of the study is to evaluate the impact of the magnetic field strength and the physical characteristics of the blend of nanoparticles using the fourth-order Runge-Kutta method, which is implemented in MATLAB. Their impact on the ensuing temperature, concentration, and velocity fields is thoroughly examined. The findings demonstrate that despite raising the temperature and solute content of the flow, increasing the volume fraction of nanoparticles decreases the flow velocity. Resistance is provided by the Lorentz force produced by the applied magnetic field, which lowers velocity and concurrently modifies heat transfer rates. It is also discovered that the existence of internal heat generation sources and thermal radiation cause a considerable shift in the fluid's temperature distribution. It is found that mass transfer coefficients, specifically the Schmidt number and Brownian motion, improve the concentration profile. The findings offer valuable insights into the solute and thermophysical transport characteristics of the system, supported by a wealth of graphical and tabular data.
