Numerical Study of Second Law Analysis Using Magnetohydrodynamics on Natural Convection in a Porous Medium with Thermal Radiation and Viscous Dissipation
Bibliographic record
Abstract
This paper focus on natural convection in the presence of an applied magnetic field for analysing entropy generation and fluid flow phenomena in a porous medium. The numerical technique adopted was the finite difference method. The parameters used for numerically analysing the fluid flows are the Rayleigh number (103 ≤ Ra ≤ 106), Eckert number (10−6,10−5,5 × 10−5) , Forchheimer number (0 ≤ Γ ≤ 1), inverse Darcy (0 ≤ γ ≤ 1), radiation (0 ≤ Rd ≤ 10), Prandtl number (Pr = 0.7,1.0,7.0,10) and Hartmann number (0 ≤ Ha ≤ 30). The numerical results were compared with existing papers and excellent agreements have been made. Findings reveal that as Hartmann increase the streamlines become distorted showing a reduction in the flow rate due to retarding impact of the Lorentz force. Enhancing radiation, leads to the intensification of the flow rate. As Rayleigh number increases entropy generation of the medium significantly increases.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
