Description:FIELD OF THE INVENTION
This invention relates to influence of inclined magnetic field, non-uniform source of heat on hybrid eg-mos2-sio2 radiative nano fluid flow with viscous and joule dissipation in convectively heated extending surface.
BACKGROUND OF THE INVENTION
The combination of non-uniform heat sources and viscous dissipation brings a lot of complexity in the study of the hybrid nanofluid flow over an elongating surface, which remains relevant and an issue of increasing interest in thermal engineering. These effects play a significant role in improving the heat transfer efficiency in highly developed projects like cooling systems, energy storage devices, as well as material processing, where a highly organized thermal control is needed. This paper examines how a non-uniform heat source interacting with a sloping magnetic field affects the nature of flow and heat transfer in a radiative EG-MoS2-SiO2 hybrid nanofluid over a convectively-heated elongating surface taking into consideration the effects of Joule heating, as well as viscous dissipation. The equations of motion of a hybrid nanofluid as a nonlinear system are developed and analytically addressed with the Runge-Kutta method in combination with the shooting technique and the findings are compared to the available literature
The effects of the concentration of the nanoparticles, the inclination angle of the magnetic field, non-uniformity of the intensity of heat source, the Eckert number, the thermal Biot number, the suction velocity and the linear radiative heat flux on the flow behavior in the vicinity of the stretching surface are studied through a thorough parametric analysis. The findings reveal that the inclination of the magnetic field and homogenous suction have a great effect on the momentum and thermal control of the fluid. When the concentration of nanoparticles is increased to 40 percent, it increases the thermal boundary layer thickness as a result of high viscous dissipation, radiative heat flux, and thermal Biot number. In general, hybrid nanofluids exhibit better thermal and momentum characteristics than conventional nanofluids, and thus their use in a high-performance heat transfer objective is possible.
