Pore-Scale Modeling in Metal Foam Heat Exchanger
Bibliographic record
Abstract
Increasing heat transfer performance of heat exchangers has been the primary focus in the thermal engineering field. Various improvement strategies have been proposed. One that is gaining considerable attention recently is application of metal foam. It offers larger heat transfer area and flow disruption that enhance overall heat transfer performance. All the while, most studies on metal foam are either experimental or simplified numerical model adopting homogeneous approach model which does not provide high fidelity information. Thus, this study is conducted to numerically investigate transport processes in metal foam heat exchangers by adopting three-dimensional pore-scale model which is expected to provide better accuracy and details on the transport processes in a metal foam heat exchanger. The numerical study was initiated with the model development, followed by numerical implementation and finally numerical investigation. The numerical investigation reaffirms past studies that the presence of metal foam does bring enhancement to the heat transfer. However, it comes with the sacrifice on the significant increase in pressure drop. The adoption of pore-scale model revealed details of transport processes inside metal foam heat exchangers.

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.
