Effects of non-Fourier heat flux and viscous dissipation on Sutterby Ag–Au/blood hybrid nanofluid flow

Abstract

: The purpose of current study is to analyze the flow and thermal behaviour of Sutterby hybrid nanofluids, with particular attention given to an inclined magnetic field, viscous dissipation, heat source, Cattaneo-Christov heat flux, and thermal radiation model. In this work, we consider the based hybrid nanoparticle in the non-Newtonian Sutterby fluid in order to investigate how much they create the enhancement in the thermal conductivity. As the inclined magnetic field interacts with the electrically conducting fluid, its impacts on flow properties are examined. A more precise description of heat flow is obtained by using the Cattaneo-Christov model, which considers the speed limitations of heat conduction. The thermal transport analysis are investigated by using the thermal radiation, viscous dissipation and heat source or sink. The physical phenomena stated above have an impact on the formulation of the governing equations of mass, momentum and energy transfer. The model is established in the form of dimensional PDEs and suitable transformations is applied to translate the PDEs into non-dimensional ODEs. A mathematical model is created, and suitable numerical technique (Runge-Kutta 4 th order) are used to find solutions. The findings demonstrate the combined impact of these variables on the fluid flow's temperature distribution, velocity profiles, and heat transfer rates. The results reveals that Lorentz force or retardation force causes the velocity profile to decrease as the magnetic field increases. When comparing the Ag/blood case to the Ag-Au/blood case based on the Sutterby Deborah number, the depth of the thermal boundary layer rapidly drops. The hybrid nanofluid's temperature rises while its velocity decreases due to the nanoparticle volume percentage parameter. The friction drag heightens along with the Sutterby Deborah number and Power-law index estimates.
