Performance and Heat Transfer Characteristics of a Latent Heat Storage Unit with Finned Tubes: Numerical Analysis on Freezing and Melting Process of n-Pentane as a Phase-Change Material
Bibliographic record
Abstract
LNG蓄冷システムを適用したボイルオフガス再液化プロセスの設計・操作法を開発するために，フィンチューブ型潜熱蓄冷装置に充填した蓄冷材（Phase-Change Material）の凝固・融解過程に関する数値シミュレーション解析を行った．本解析では，前報で報告したパイロットプラント実験結果に基づき，厚肉円筒モデルを採用してフィンチューブ周りの伝熱特性と相変化挙動を表すとともに実プラント操作に適用するために計算方法の簡略化を図った．数値解析による計算結果は実験結果と良い一致を示し，本モデルは実用プラントと同規模の伝熱管長を有する蓄冷装置の性能を精度良く推測できることがわかった．この結果，本モデルは蓄冷装置を含むプロセス設計や運転に有効に活用することができる．また，管内二相流体の凝縮域の長さが蓄冷装置のフィンチューブ全長を超えると，液化時間や放冷割合が急激に低下することがわかった．

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.
