Numerical Investigation of Magneto-Hydrodynamics Mixed Convection in a Square Cavity for Various Shaped Conducting Obstacles Placed at the Center
Bibliographic record
Abstract
A numerical study of mixed convection in a square enclosure from a heating element to a cold moving wall is performed under the isothermal heating conditions.The heater is placed at the bottom boundary and the cold upper wall moves horizontally towards right side with constant velocity.The lateral walls are insulated.The study includes the thermal performance of nanofluid for various shaped obstacles kept at center of the enclosure.The application of hydro-magnetism with uniform and constant magnetic intensity throughout the bottom wall is considered.The heat convection is studied at two Richardson number (0.01 and 10), four percentage volume of silver nanoparticles (0%, 2%, 5%, and 8%) and four Hartmann number (0, 10, 20, and 50).Grashof number, Prandtl number, and Reynolds number have a constant value of 104, 6.2 and 100 respectively.The obtained results indicate the suppression of heat fluxes with increasing intensity of magnetic field whereas it increases with increasing Richardson number and percentage volume of the nano-material in the base fluid.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
