Özet
The current study investigates the influence of suction, Ohmic heating and viscous dissipation on transient radial flow and heat transmission characteristics of a tetra-hybrid nanofluid via a stretching surface. Such effects play a critical role in several manufacturing and production processes involving stretching sheet configurations. Using relevant similarity transforms, the governing unsteady momentum and energy equations are reduced to non-linear ODEs (ordinary differential equations) forms. These resulting ODEs are resolved numerically via the Keller–Box technique. In addition to numerical analysis, statistical techniques, including multiple linear regression analysis, are employed to measure the response of key physical factors on the resulting flow and thermal behavior. The results demonstrate that suction and magnetic forces significantly suppress fluid motion, also, the synergistic impact of magnetic field strength and viscous dissipation (represented by the Eckert number) enhance the heat transfer performance. Variations in the surface frictional factor and the Non-dimensional temperature gradient are examined for diverse values of the Eckert numbers, magnetic, unsteadiness and suction parameters. Strong correlations in between the regulatory factors and the response variables are revealed by the regression analysis, and this is corroborated by a high coefficient of determination (R²). Excellent alignment is found when the results are assessed against previously published data, supporting the current model and numerical method. The findings indicate that the proposed configuration is highly relevant to practical implications such as heat exchangers and electronic device thermal controlling systems, where specific flow control and enhanced heat transfer can improve the performance, stability and compact operational costs.
