Entropy analysis on EMHD 3D micropolar tri-hybrid nanofluid flow of solar radiative slendering sheet by a machine learning algorithm

Abstract

The purpose of this paper is to analyze the heat transfer behavior of the electromagnetic 3D micropolar tri-hybrid nanofluid flow of a solar radiative slendering sheet with non-Fourier heat flux model. The conversion of solar radiation into thermal energy is an area of significant interest as the demand for renewable heat and power continues to grow. Due to their enhanced ability to promote heat transmission, nanofluids can significantly contribute to enhancing the efficiency of solar-thermal systems. The combination of silicon oil-based silicon (Si), magnesium oxide (MgO), and titanium (Ti) nanofluids has attracted attention for their ability to improve the performance of solar-thermal systems. The present study discloses a new approach for intelligent numerical computing solving, which utilizes an MLP feed-forward back-propagation ANN and the Levenberg-Marquard algorithm. The collection of data was conducted for the purpose of testing, certifying, and training the ANN model. The Bvp4c solver in MATLAB is utilized to solve the nonlinear equations governing the momentum, temperature, skin-friction coefficient, and Nusselt number. The characteristics of numerous dimensionless parameters such as porosity parameter $$\left(K={0.0,2.0,4.0}\right)$$ K = 0.0 , 2.0 , 4.0 , vortex viscosity parameter $$\left({R}_{1}={0.5,1.0,1.5}\right)$$ R 1 = 0.5 , 1.0 , 1.5 , electric field parameter $$\left(E={0.0,0.1,0.2}\right)$$ E = 0.0 , 0.1 , 0.2 , thermal relaxation time $$\left(\Lambda ={0.01,0.10,0.20}\right)$$ Λ = 0.01 , 0.10 , 0.20 , heat source/sink parameter, $$\left(Q=-{0.3,0.0,0.3}\right)$$ Q = - 0.3 , 0.0 , 0.3 thermal radiation parameter $$\left(R={0.5,1}.{0,1.5}\right)$$ R = 0.5 , 1 . 0 , 1.5 , temperature ratio parameter $$\left({\theta }_{w}={0.5,1.0,1.5}\right)$$ θ w = 0.5 , 1.0 , 1.5 ,nanoparticle volume fraction $$\left(\phi ={0.00,0.02,0.04}\right)$$ ϕ = 0.00 , 0.02 , 0.04 on Si + MgO + Ti/silicon oil micropolar tri-hybrid nanofluida are analyzed. The ANN model engages in a process of data selection, network construction, training, and evaluation of its effectiveness through the utilization of mean square error. Tables and graphs are used to show how essential parameters affect fluid transport properties. The velocity profile is decreased by higher values of the porosity parameter, whereas the temperature profile is increased. The temperature profile is inversely proportional to higher values of the electric field parameter. The micro-rotation profiles reduced by expanding values vortex viscosity parameter. It has been determined that entropy generation and Bejan number intensifications for enlarged nanoparticle volume fraction.

Numerical Heat Transfer on Sutterby Tetra Hybrid nanofluid for Biomedical Application

“…Porous media find diverse applications in science and engineering, ranging from electronic cooling, thermal insulation, biomedical applications, and geothermal systems, to drug delivery and tissue replacement. This has stimulated academic and research interest, prompting further exploration of porous media-related challenges in real-world scenarios [18][19][20]. In the study by [21], the effects of magnetic field, mixed convection on the flow of mono and hybrid nanofluids within porous media, is explored.…”

“…Table 3 shows that when these parameters are reduced, the skin friction values for mono nanofluid decrease more than those for tetrahnf. Nusselt number decreases when the parameters Nt and Nb are raised in figure (18)(19). The Shx is a dimensionless used in mass-transfer actions.…”
