Numerical Simulation of High-Temperature Gas Flow Rate Control Valve with Laval Structure by Fluid-thermal-structure Coupling
Bibliographic record
Abstract
High-temperature gas flow rate control valve (GFRCV) with Laval structure is the core component of gas control system. The influence of fluid-thermal-structure (FTS) coupling deformations on the characteristics of GFRCV is a noteworthy issue. In this work, numerical simulations by two-way FTS coupling method and single computational fluid dynamics (CFD) method are conducted to analyze the velocity distribution, pressure distribution, deformations and flow characteristics of GFRCV with Laval structure. Variation regularities of velocity, pressure, and flow characteristics calculated by two-way FTS coupling method are more in line with the actual working conditions in consideration of the influence of FTS coupling deformations on flow characteristics, which reveals that two-way FTS coupling numerical calculations are more meaningful in engineering application.

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.
