| Summary: | A hybrid nanofluid is comprised of a (Ethylene glycol) base fluid component and (Copper and Aluminium oxide) nanoparticles, and the nanoparticles are scattered inside the Ethylene glycol. Integrating nanoparticles into a base fluid (Ethylene glycol) can significantly enhance its thermal conductivity, which in turn can boost the base fluid's rate of heat transfer. In addition, the dynamics of viscous fluid together with nanoparticles is quite interesting and has a large of applications in the industrial sector. The current predominately predictive modeling investigates the flow of the hybrid nanofluid via a stretchable stationary disk in the presence of heat source/sink. A progressive modification in he energy equation is done by utilizing the Cattaneo-Christov heat flux expressions. This theory provides predictions for the features of the thermal relaxation time of the liquid on the boundary layer flow. Further, the study focuses on the features of the Lorentz force resulting from the applied of a magnetic field perpendicular to the disk. The similarity approach is used to obtained the dimensionless ordinary differential equations.The bvp4c approach in Matlab is utilized as a numerical method for the solution. All the solutions are obtained through graphical form. According to the results, the thermal profile is reduced by adjusting the thermal relaxation time parameter. Motion of the hybrid nanofluid slows down by enlarging the magnetic force parameter. Additionally, the effect of the heat source significantly increases the thermal profile. It is noted that the temperature field is enhanced in the case of a larger Lorentz force. Moreover, the increase in volume fraction concentration intensifies the thermal distribution, but the velocity is diminished due to the effect of viscosity. |
